# Troubleshooting Check the below if you have any issues during installation or use ## Installation Issues After installation make sure you have done a `dev/build` you may also need to flush the admin view by appending `?flush=1` to the URL like `http://yoursite.com/admin?flush=1` ## UserForms EditableFormField Column Clean task This task is used to clear unused columns from EditableFormField The reason to clear these columns is because having surplus forms can break form saving. Currently it only supports MySQL and when it is run it queries the EditableFormField class for the valid columns, it then grabs the columns for the live database it will create a backup of the table and then remove any columns that are surplus. To run the task login as Admin and go to to http://yoursite/dev/tasks/UserFormsColumnCleanTask ## My CSV export times out or runs out of memory You likely have too many submissions to fit within the PHP constraints on your server (execution time and memory). If you can't increase these limits, consider installing the [gridfieldqueuedexport](https://github.com/silverstripe/silverstripe-gridfieldqueuedexport) module. It uses [queuedjobs](https://github.com/silverstripe-australia/silverstripe-queuedjobs) to export submissions in the background, providing users with a progress indicator.
