#41375 closed defect (bug) (wontfix)

Editor not working in older versions of Safari, or Roccat Browser on older versions of macOS

Severity: normal Version: 4.8

Focuses: Cc:


When using WordPress 4.8 on Safari 5 or Safari 6 (possibly Safari 7) the editor doesn't show the two rows of tools and the content area is blank. The same thing happens when using Roccat Browser on macOS 10.5, 10.6 and 10.7.

The errors which show in the console are:

ReferenceError: Can't find variable: URL - that's line 11 on tinymce.min.js
ReferenceError: Can't find variable: tinymce - that's line 1 on plugin.min.js
ReferenceError: Can't find variable: tinymce - that's line 10043 on post.php

All versions of WordPress 4.7 have worked perfectly.

Hi @orbitcarrot. Unfortunately I don't have an old Safari version to see exactly what's going on. I think support for older WebKit browsers was removed together with support for old IE. It may be beneficial to pinpoint the exact place this breaks. You can do that by testing different versions of TinyMCE here: (select the version from the drop-down menu on the left).

Ultimately this should be reported upstream at the TinyMCE bug tracker:

  • Resolution set to wontfix
  • Status changed from new to closed

Older Safari versions are no longer supported in wp-admin, either in the block editor or the classic editor.

Closing as wontfix as this is the expected behaviour.
