I added organic groups module to a drupal website. For some reason the website crashed and gives the following error:

Fatal error: Unsupported operand types in /home/content/39/7384539/html/salvare12/sites/default/modules/og/includes/og.info inc on line 115

I removed the organic groups module manually and disabled it in the database. But then it gives a file missing error. I have uploaded the organic groups module once again but it does not work.

How can this be fixed? Is there some safe mode in drupal, to which i can revert when such an error occurs?

  • Have you run update.php in the URL?

Try deleting the row for the og module in the system table. Then run a query for each database table beginning with cache_:


This should make Drupal forget anything it knew about organic groups (this is how to clear the cache manually).

I'd suggest keeping your modules in the standard location which is /sites/all/modules rather than /sites/default. I don't know if thats part of the problem here but it might be.


Also, I'd get to know drush and use that to disable and uninstall (where available) modules until your site is back up again.
