When requesting support please follow these steps:
1. Update all JEvents add on's first, via the Joomla! Updater 2. Copy and Paste the JEvents Support Information from the JEvents Control Panel. 3. If you get a 500 error OR white page, enable Maximum Error Reporting in Joomla! Global Config and visit the page again, this should give you a more detailed error and help us provide a prompt response.
I disabled the following plug-ins from the type "Finder": Motore di ricerca - Categorie Motore di ricerca - Contatti Motore di ricerca - Contenuti Motore di ricerca - Newsfeeds Motore di ricerca - Link web But the problem was not solved.
Then I disabled: Smart Search - Jevents, and now my JEvents calendar works well and also I'm still able to search contents in my application.
the only place that data is inserted in the #__finder_tokens table is in the file administrator/components/com_finder/helpers/indexer/indexer.php at lines 1213-1240 for Joomla 2.5 and the file administrator/components/com_finder/helpers/indexer/driver/mysql.php at lines 580-607. In either case the code looks watertight and should not generate a different number of columns.
Can you give me your error message in more detail and cut and paste the relevant lines of code from the file mentioned above so I can see what you have on your server.
