Editor not working after update and Page Title

I recently updated to Firefox 11.0 and now any text editor I use does not work. It works fine in other programs and the Article manager. I'm running Joomla 1.5.26. Also when you click on a category the page title says ED_CATEGORY_PAGE_TITLE.

Hi

I recently updated to Firefox 11.0 and now any text editor I use does not work

=> Go to Extensions -> Plugins manager, find the System - Mootools upgrade plugin, publish it. After that, this issue will be solved.

I'm running Joomla 1.5.26. Also when you click on a category the page title says ED_CATEGORY_PAGE_TITLE.

=> You are using a different language file than English and that's causing the issue. When you upgrade from old version to new version, usually, there will be new language strings added to English language file and you will need to add these language strings to the language file of your language as well . Open the file language/en-GB/en-GB.com_eventbooking.ini, compare it with your language file and add the missed language items. After that, it will work as expected .
