RTEs accessibilityicons missing in TYPO3 7.6

After upgrading my project from TYPO3 4.x to TYPO3 7.6 there were many broken icons in the front-end:

<a href="mailto:mail@example.com" class="mail">
  <img src="typo3/sysext/rtehtmlarea/res/accessibilityicons/img/mail.gif" alt="">mail(at)example.com
</a>

The directory typo3/sysext/rtehtmlarea/res/accessibilityicons/img/ is not there anymore. How to fix that?

Solution

As the directory structure of the extension rtehtmlarea is aligned to the Extbase structure so that the location of some directories changed (Thx to Georg Ringer). The icons are located in typo3/sysext/rtehtmlarea/Resources/Public/Images/ now.

You can easily change the whole content with this SQL snippet:

UPDATE tt_content 
  SET bodytext = REPLACE(bodytext, 
    'rtehtmlarea/res/accessibilityicons/img/', 
    'rtehtmlarea/Resources/Public/Images/');

This rewrites all occurrences of the icons to the new path.

Sometimes also this old path is used: typo3/sysext/rtehtmlarea/htmlarea/plugins/TYPO3Browsers/img/mail.gif You can adjust obove SQL statement for this too.

Please backup your database before.
