Current system: Windows Server 2012 with IIS 8 Wordpress 4.4.2 PHP 5.5 MySQL 5.1.73

I am currently running CiviCRM 4.6.14 on a live system on which our users have found a problem when ordering custom date fields. This ordering issue does seem to be resolved in the latest version so I need to upgrade. I can upgrade to the latest LTS (4.6.36) without a problem but this does not resolve the issue and moving away from the LTS is proving difficult. I have tried upgrading to 5.0.1 and receive a HTTP 500 error after clicking the 'Return to homepage' link once the upgrade is complete. I then restored my server snapshot take after the successful 4.6.36 upgrade and tried 4.7.31 as this was the stable version released at the same time as the LTS version I can update to. Again, HTTP 500 error after the upgrade.

No errors are shown during the upgrade which is reported as successful.

Am I missing instructions somewhere for migrating out of the LTS branch or can someone help with the error please? My CiviCRM lof file is here: https://pastebin.com/Hw8qhmNN

Any help would be appreciated.

Thanks Russell

After looking Civi log it seems that problem is with civicrm_uf_group.frontend_title field. I would suggest you to do incremental upgrade i.e

Upgrade CiviCRM to 4.6.x to 4.7.30 Upgrade CiviCRM to 4.7.31.

On a separate note make sure you disable all the CiviCRM extension or wp plugin and also disable wp post or pages that have CiviCRM profile shortcode before upgrading.

  • disable logging too perhaps – petednz - fuzion Apr 24 '18 at 20:20
  • Thanks for the suggestion of disabling the CiviCRM extensions - disabling the 'CiviCRM Postcode Lookup' extension completes the update and successfully launches CiviCRM. I now have an issue of custom data not displaying when the Tab is set as 'Tab with Table'. I'll investigate further and post a new topic if required. – Russell Apr 25 '18 at 13:26
