WP BLOCKED AFTER UPGRADE TO 2.2.4 in WP 3.8 - SOLVED!

[OpenRing.net]

If after upgrading myEventON to the latest release your WP site is blocked, you can not access to it and you get this:

Warning: require_once(AJDE_EVCAL_PATH/classes/class-evo-addons.php) [function.require-once]: failed to open stream: No such file or directory in /home/your-domain/public_html/your-wp-main-folder/wp-content/plugins/eventon-csv-importer/eventon-csv-importer.php on line 601

Fatal error: require_once() [function.require]: Failed opening required 'AJDE_EVCAL_PATH/classes/class-evo-addons.php' (include_path='.:/usr/local/php53/pear') in /home/your-domain/public_html/your-wp-main-folder/wp-content/plugins/eventon-csv-importer/eventon-csv-importer.php on line 601

I fixed everything by doing these steps:

- delete via FTP "/wp-content/plugins/eventon-csv-importer/" folder.
- refresh via browser the admin page, now it's possible.
- the system tells you all EventON AddOns need "/wp-content/plugins/eventON/" plugin and folder to work (even if it's already there!!)
- do not worry and delete "/wp-content/plugins/eventON/" folder via FTP.
- now by WP Admin reinstall myEventON main part via FTP upload.
- check everything, but it would be ok

Jacopo, thanks for sharing your solution. In your FTP did you have multiple copies of eventON installed?
