I am not a 100% certain how this happened because some time has past since I did an upgrade, yet the upgrade could be the reason I am getting the following error:
Fatal error: require_once(): Failed opening required '/public_html/sites/all/modules/nodeorder/nodeorder.pages.inc'
All the page needs to do is load a different photos based on the category that the user selects. However when they select a category that is when the error appears. Please note that everything else on the site works.
Keep in mind that I inherited this site and I am NOT a Drupal guy.
Maybe the following will help, but again if you ask me to do/try something please be specific and explain it to me step-by-step so I do not get it wrong.
Database system: version 5.5.62-cll
Database updates: Out of date
Drupal core update status: Not secure! (version 7.67 available)
PHP extensions: Enabled
PHP memory limit: 256M
PHP register globals: Disabled
Note: I am not certain about exactly what version I upgraded from but it seem to me it was a very early version of 7. How do I go about upgrading the PHP? Also, is there any troubleshooting that I can do on my end to see if something got corrupted?
