I am unable to access the Civi administrator section on a website using Joomla 3.7.5, Civi 4.7.23 and running on PhP 7.0. Joomla portion works fine, but when I access Components/Civicrm from the Joomla backend, I get a blank page with no error messages (although Joomla debugging is turned on). Using Firefox Developer edition's debugger the response is "Page has no sources".

I then created a new Joomla user with superuser privileges. Logged in and got the following message (screenshot attached). errormessage

Since I can't login to change settings to display all errors and turn on backtrace, how do I troubleshoot? Any help would be appreciated.

Thanks, Kate

  • Hi GrannyKat - you took the time to ask a question, and others make the effort to provide useful answers. It would be good if you could acknowledge them, and ideally Accept (and +1) or let them know via comments why it didn't apply to your situation

You have two options for troubleshooting:

  • Debug and backtrace info should also be in your CiviCRM logs, stored in the ConfigAndLog directory.
  • You can enable debug and backtrace by adding these three lines to civicrm.settings.php:

    global $civicrm_settings; $civicrm_setting['Developer Preferences']['debug_enabled'] = TRUE; $civicrm_setting['Developer Preferences']['backtrace'] = TRUE;

  • You can also set these under menu Administer>System Settings>"Debugging and Error Handling"

  • @BruceW ordinarily true, but in this case they're saying they weren't able to reach the Civi admin screens. Sep 20, 2018 at 23:02
