https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=28927 --- Comment #1 from Fridolin Somers <fridolin.somers@biblibre.com> --- Created attachment 124267 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=124267&action=edit Since preference OpacMainUserBlock is an HTML customization, there is an HTML tags with id="opacmainuserblock" and one with id="OpacMainUserBlock". I think template block "koha_news_block" should add a class (lowercase) instead of an id. It fixes the bug and also it may be used several times in same page in the future. Test plan : 1) Create an HTML customization for OpacMainUserBlock with some text 2) Go to OPAC main page 3) Check HTML code of the page 4) Check you see class="opacmainuserblock" and not id="OpacMainUserBlock" -- You are receiving this mail because: You are watching all bug changes.
