2016 – Apps loaded in the App Catalog do not have the correct app version or product ID

I am working with a client who has just set up a new SharePoint 2016 website on his server. You've created an app catalog, but when I load a custom SharePoint app, the app catalog does not read the version from the AppManifest.XML and sets the version to, nor does the app become a product ID assigned – the product ID is left blank.

The same app is uploaded to other sites with the correct metadata.

Does something have to be configured to make the App Catalog library behave like an App Catalog?

thank you in advance

Could not start django – gunicorn.service: Device is not loaded properly: Invalid message

I'm having trouble configuring Gunicorn. So far, I have pulled my Django code onto the server, created a Virtualenv for Python 3.6, installed Django Gunicorn Psycop2 with Pip3 and that's all right.

I can run the Django development server and see my undesigned site and have successfully posted to the database through the admin site for it to work. I then started it directly with:

gunicorn django_version.wsgi:application --bind

and again I could see my non-styled page. I also tried:

/srv/pcc_django/django_env/bin/gunicorn --workers 3 --bind unix:/srv/pcc_django/django_version/django_version.sock django_version.wsgi:application

and that started without mistakes. So my next step was to write a .service file:

Description=gunicorn daemon

ExecStart=/srv/pcc_django/django_env/bin/gunicorn --workers 3 --bind unix:/srv/pcc_django/django_version/django_version.sock django_version.wsgi:application


and try:

systemctl start gunicorn.service

I get the above error message and it reads:

systemctl status gunicorn.service

and it gives the following message:

but there is something strange going on, because when I do it:

I get the following timestamp:

So I am not sure if this message refers to an incorrectly starting Gunicorn service. What did I miss that prevents Gunicorn from being started as a service?

PHP – How to check in CentOS 7.7 which process takes 1 minute because the page is loaded slowly (TTFB 1 minute)

I am using CentOS version 7.7.
A few days ago my frontend page (not whole website) is TTFB exactly 1 min.
How can I check which process causes this?
I use PHP 7.3 php-fpm ON

Is there a way to check which process causes the first byte to wait 60 seconds?


This error occurred several times a day. The page availability is therefore 88%. My start page was down because of 12% (TTFB 1 minute). Please help, it is very urgent for me

Why do you get these highly loaded backlinks | Not? Forum Promotion

Once upon a time there was a question for me. Is it still possible to visit a site without pop-ups, not constantly wanting to email me, or trying to sell me something? In my opinion, can I set up a free forum site? To find the answers I'm looking for in my project discovery in the gloomy world of, "Create your own website for free." I found the following and quickly switched from a forum to an article-based blog.

Backlinks. Everyone wants them, but as a first contribution, we briefly delve into the grim world of popularity.

First, let's bring the bad news.

Forum PromotionIn case you do not want to get any further

First, forums are becoming increasingly popular, and that is partly because they are a niche platform for issues.

Second, Google will not faint over the content of individual sentence comments. Google is searching for quality content with Google updates for Hummingbird (and other animal-related updates). What information and knowledge do you have in your specific forum topic that sets the world on fire and causes others in your niche to recognize you as the leading expert and link to you? The rhetorical answer is probably "none", and for that reason no link is made to you.

Third, as much as everyone loves their knitting patterns, they will not become viral no matter how many backlinks you have.

If you want to advertise in the forum, you will proverbially whip out a dead horse. You can have any number of links to pre-World War I cigar lighter collectors' forums and cat appreciation companies, but you know, and Google knows that's not going anywhere.

Forum recognitionIn case you do not want to get any further

There is a business claim that goes as follows: "90% of the business is marketing and 10% is sales." Linking to your own forum by writing an article on free authoritative websites such as academia.edu, google + and Issuu is worth fifty backlinks compared to links from other unknown forums. Google takes note of links from websites like these. Join other sites that relate to your forum content and link them to a link to your own website. You do not have any long-form articles in your forum yet, but you expect search engines to send you viral comments, such as: "Yes, I think World of Warcraft is good too."

Will my forum be viral?In case you do not want to get any further

The answer is no! Forums are fine, depending on what you want. As a hobby, learning pleasure or niche subject they are ideal. For example, you might even want to write about your professional skills and create a visual CV portfolio and attach a link to your resume that others may want to address and acquire the knowledge they need for themselves. Maybe you think that others might be interested in your passion for yoga? Or did you travel a lot? Food is always popular … That's fine, but you will not get thousands of visitors a day, unless you're already famous or have a $ 1 million marketing budget. You will not be the next Facebook no matter how much effort you invest. Treat a forum as what it is, as a pastime.

8 – Why is the preview of the loaded image not displayed?

When I load an image into a Drupal 8 form, JS errors appear in the console and the file link is not displayed. I have a limit of 10 MB per file in Drupal. If I load a picture of 1 MB or less, it works. If I load an image larger than 1 MB, it will not load and the consoles will have errors:

Enter image description here

I load an image of less than 1 MB, it works:

Enter image description here

I upload an image of more than 1 MB, it is an error (console error and no warning):

Enter image description here

The form fields and my server are configured correctly:

Enter image description here

The server and Drupal seem to set me right. How can I fix this?

In addition, the user will not be warned if the limit is exceeded. Drupal has a lot of bugs that let the user run away and cause him to drop the form.

jquery – Document.ready does not fire when the page / ready / init is loaded

I am building an embedded web server. My web pages are sent to the browser. When I click on the navigation bar and ask for a new page, the page loads, but (document) .ready (function () does not fire, so I use this function to start loading data from the server via Ajax calls – but never called.

HTML and scripts are all in the same file.

Using Chrome – Once the page has been displayed (without calling ready () – if I want to refresh the page – it fires ready.

My abbreviated page is below.

I tried to replace
$ (document) .ready (function ()
$ (document) .on ("pageinit", function (event)
and some others.

magento2 – YouTube video is not loaded on the product page tab

I have an attribute: Video link that I fill in with a YouTube video embed link:

When I try to display the video on a product tab in an HTML code, the video is not displayed and no errors occur.

    $videolink = $_product->getVideoLink();

If I manually add the embed code, the video will be displayed:

I also set a Google API key in the Configuration> Catalog> Catalog> Product Video

How can I display the video on a product tab?

Samsung Galaxy S 10 – Some websites can not be loaded via USB tethering

I'm sharing the Internet from my Samsung Galaxy S10 + to my HP Pavilion 15 n208tx laptop via USB tethering. Surf speeds of up to 10 Mbps are achieved on my phone, but tethering can not load many websites. I am using the Tethered Type C USB cable supplied with my phone.

Example of strange behavior:
