I run a number of websites and have recently had to embed videos (mostly Vimeo but not exclusively) in one of them. I have another site where I have successfully embedded the code: & # 39; set plain text, insert embed code, select full HTML & # 39; – Bingo is all right.
If I try the exact same procedure on the second site, the system simply places paragraph marks around the code as if I were not inserting plain text first. I have searched the two websites and cannot see where the settings for the editor (in both cases CKEditor version 7.x-1.19) differ, but I cannot see anything. Ealier posts on the subject suggest looking at / admin / settings / filter / list that are not present in my Drupal 7 installation. I know I could start installing modules to fix this, but I can't see why this works on one site and not another. I use different templates on both websites, but why should that make a difference (and switching to Bartik on the problem website doesn't make any difference anyway). Any suggestions, such as where to look at the list of allowed HTML tags in D7?
