Just updated our WP install from 4.7.22 to 4.7.23 -- but can't run the db update script, because whenever I rename the 4.7.23 folder to civicrm, I subsequently get 500 internal server errors while trying to load any civicrm pages. Error log indicates a problem at line 41 in CRM/Core/Config.php, which is require_once 'api/api.php'; ... so I searched the previous working iteration (it runs fine when I switch back to 4.7.22) and there is no mention of api/api.php anywhere. So I assume this line is new in 4.7.23, and I have to wonder why it's making civicrm completely unusable for our site.

Ideas?

More detail from the error message:

PHP Fatal error: require_once(): Failed opening required 'api/api.php' (include_path='.:/wp-content/plugins/civicrm/civicrm:/wp-content/plugins/civicrm/civicrm/packages:/wp-content/plugins/civicrm/civicrm/vendor/tecnickcom:/wp-content/plugins/civicrm/civicrm/vendor/phpseclib/phpseclib/phpseclib:/wp-content/plugins/civicrm/civicrm/vendor/pear/pear_exception:/wp-content/plugins/civicrm/civicrm/vendor/pear/auth_sasl:/wp-content/plugins/civicrm/civicrm/vendor/pear/net_socket:/wp-content/plugins/civicrm/civicrm/vendor/pear/net_smtp:/wp-content/plugins/civicrm/civicrm/vendor/pear/validate_finance_creditcard:.:/wp-content/plugins/civicrm/civicrm/:/wp-content/plugins/civicrm/civicrm//packages:.:/usr/lib/php:/usr/local/lib/php') in /wp-content/plugins/civicrm/civicrm/CRM/Core/Config.php on line 41

First, let the record show that I am an idiot.

After uploading 4.7.23 (the new version) to /wp-content/plugins, I neglected to copy the pre-existing civicrm.config.php into /wp-content/plugins/civicrm4.7.23/civicrm ... thereby depriving the system of (at very least) a working value for $civicrm_root.

It was suggested to me that my civicrm.config.php was probably off, and I checked it just to make sure the $civicrm_root value made sense. The value was good, but the file I was checking was located outside of the plugins directory -- this was a clue, and I missed it. As I said, I'm an idiot.

Of course, once I copied the old civicrm.config.php into the new /wp-content/plugins/civicrm/civicrm, everything worked perfectly. Except for CRON jobs, of course -- but that's another matter.

Ok that's odd - require_once 'api/api/php'; has been there since CiviCRM switched from SVN to GitHub.

https://github.com/civicrm/civicrm-core/blame/master/CRM/Core/Config.php#L41

enter image description here

So something else is going on; do you perhaps have two civicrm directories in your file structure? Simply renaming 4.7.22 to civicrm-old and 4.7.23 to civicrm will not work. Make sure to move the civicrm-old completely out and away.

Added: make sure you do everything in exact order:

  • move 4.7.23 code out and away
  • revert back to 4.7.22 db
  • move 4.7.22 code -> civicrm
  • make sure it's working
  • remove 4.7.22 code out and way
  • put the 4.7.23 code -> civicrm
  • run the database upgrade script
  • make sure it's working

  • Thank you for your answer, Karin. You're absolutely right: require_once 'api/api/php'; is right where it should be in 4.7.22 -- I was in a rush to post my question, and I made the stupid mistake of trusting the search engine in my file manager when it found the string in 4.7.23 and didn't find it in the previous version. I had to open Config.php in 4.7.22 just now to see that it was there. In past updates, I've never had a problem playing the name game with the civicrm directories. Upload the new, rename the new and the old, and run the db update script ... but not this time.

  • That said, moving the old civicrm directory out of my root directory doesn't help. When I do that, I still get a 500 error with every civi page I try to access. Something is amiss in 4.7.23, but I have no idea what.

  • There are no widespread install issues for 4.7.23 so this is specific to your setup/procedures. Added some notes to my answer.

  • Finally realized my omission of pasting the old civicrm.config.php into the new civicrm/civicrm folder was breaking the system. There was no need to move 4.7.22 away -- once I renamed the civicrm folder, it became effectively inactive, and the newly renamed civicrm folder (previously 4.7.23) became active. Now that the current version is installed & working and the db was successfully upgraded, I can remove the 4.7.22 folder.
