Cloudflare kills dashboard + Relationship tab error. Any ideas?

Question

Drupal 6.36; CiviCRM 4.5.8

I am experiencing two problems after making changes to my site. Not sure if the problems are related. I will start troubleshooting but any guidance would be very helpful.

1. Civi dashboard loading icon spins and dashlets don't load. This may be related to us installing Cloudflare (http://forum.civicrm.org/index.php/topic,27176.msg142612.html#msg142612).

2. Relationships tab generates error on click. Screen loads but the relationships list doesn't open. The following two popups appear:

DataTables warning: table id=DataTables_Table_0 - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1

DataTables warning: table id=DataTables_Table_1 - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1

Clicking the Add relationship button opens the dialogue and allows it to be completed, but on saving the above errors appear again.

Background:

• Moved the site to a faster server with no apparent problems
• 6 hrs later...
• Upgraded Drupal 6.36 security release. All seems fine.
• Tried to install Civi4.6.4 but it errored out so I reverted to the 4.5.8 backup. It was late and I didn't copy the error :-(
• Implemented Cloudflare. Civi is appreciably faster. Cloudflare needs www. domains so I set up a redirect in htaccess and updated the Civi paths and resource URLs. Also cleared all caches

Thanks Davy

Answer 1

Disabling Cloudflare or switching off popups as suggested didn't help. Neither did setting up a Cloudflare PageRule to bypass all Civi pages

But this worked:

I followed the instructions here (http://wiki.civicrm.org/confluence/display/CRMDOC/Ensuring+Schema+Integrity+on+Upgrades) to clean up my database schema, and then the upgrade to 4.6.4 worked - and fixed the problems.

Answer 2

First (and easiest to do) disable Cloudflare and see if the site operates correctly. Disabling Cloudflare is super easy to do.

This may be related to the pop-up forms in recent versions of CiviCRM. You can go to civicrm/admin/setting/preferences/display and unselect "Enable Popup Forms" and see if that corrects the problem as well.
