file Fatal error: require_once(): Failed opening required

4 years 2 months ago #2398 by Frank Collins
Using jm_finance template, and recently upgraded to Joomla 3.8.0, using PHP 5.6.31. Now getting following error when some users are trying to access pages they don't have permissions to access:

Fatal error: require_once(): Failed opening required 'public_html/libraries/joomla/document/html/renderer/head.php' (include_path='.:/opt/alt/php56/usr/share/pear:/opt/alt/php56/usr/share/php') in /public_html/templates/jm_finance/error.php on line 27.

Line 27 in mentioned "error.php" says:


Is this being caused by an incompatibility or configuration problem with jm_finance template?

How can I fix this?

    Could you share your URL?

    Before updating Joomla! you should follow below steps
    1. Full Backup your site including database You can use e.g Akeeba Backup
    2. Update Page Builder to the latest version (2.5.3, If page builder is installed in your site.)
    3. Update other third-party extensions Go to Extensions/Manage/Update
    4. Then update your site to Joomla 3.8

    1) I did backup my site before upgrading to Joomla 3.8.0.
    2) I don't have Page Builder installed.
    3) All my other extensions are updated.
    4) I had already installed the "plg_system_helix_j3_v2.5.zip" that I downloaded on 07/14/2017.

    However, the behavior is also occurring with protostar and beez3 templates, so it's probably something besides the JM_Finance template.
