I recently tried to upgrade my neatline plugins. I was on very old Neatline plugins. I simply upgraded what I had to the most recent version.
During the upgrade process, I got an error, that I first needed to upgrade from 1.x to 2.0 Neatline before upgrading to the most recent version.
I then upgraded to 2.0, but got a new error (Zend_Db_Statement_Mysqli_Exception omeka), that one of the databases for migration already existed.
I went to mysql database interface on cpanel and didn't see any duplicates. Figured I could just empty the database. That didn't work. Then thought maybe the upgrade wanted to create it, so I deleted the database.
None of these solutions worked. I then tried to reinstall the old version I had before this upgrade process, and now my entire site has crashed (?) or at least it is not visible, public, and cannot access /admin.
I now get the following page when I go to my site:
"Notice: Use of undefined constant HELPERS - assumed 'HELPERS' in /home/mappin6/public_html/plugins/Neatline/plugin.php on line 47
Warning: require_once(HELPERS) [function.require-once]: failed to open stream: No such file or directory in /home/mappin6/public_html/plugins/Neatline/plugin.php on line 47
Fatal error: require_once() [function.require]: Failed opening required 'HELPERS' (include_path='/home/mappin6/public_html/application/libraries:/home/mappin6/public_html/application/models:.:/usr/lib/php:/usr/local/lib/php:/home/mappin6/public_html/plugins/ExhibitBuilder/models:/home/mappin6/public_html/plugins/Geolocation/models:/home/mappin6/public_html/plugins/SimplePages/models:/home/mappin6/public_html/plugins/DublinCoreExtended/models:/home/mappin6/public_html/plugins/CollectionTree/models:/home/mappin6/public_html/plugins/Neatline/models') in /home/mappin6/public_html/plugins/Neatline/plugin.php on line 47"
At this point, I'm not sure how to recreate my steps and fix what I had.
I don't even want the data from the old Neatline exhibits. They were just tests, I really just want to install all new Neatline plugins. This shouldn't have made my entire site have errors.
Any helps is very much appreciated, because at this point I have no idea what to do next.
