Our VPS provider downgraded PHP from 7.2.2 to 5.6. Is there a list of changes that we need to back out to support 5.6 running OJS 2.4.8.5? (We asked them to investigate what it would take to install PHP 5.6 …they translated that to “INSTALL PHP 5.6”!)

I don’t think OJS 2.4.8-5 implements any code which requires PHP7 (at least in core). Are you getting specific errors in your error log? That said, PHP 5.6 is beyond end-of-life and PHP 7.x is standard. It is strongly recommended to use PHP 7.x.

Per these following links, it seems that there are pieces that were modified for php 7.x [image] OJS 2.4.8 and PHP 7.2 Compatibility Software Support If you don’t have local modifications to your installation, it would be pretty straightforward for someone to upgrade your…

A substantial amount of work was done to remove deprecated or obsolete PHP 4.x or 5.3.x/5.4.x functions and syntax which would cause warnings and errors in PHP7. That work did not generally make the code incompatible with PHP 5.6. These changes would not need to be reverted. Code which is PHP7-on…

Thanks. Upon downgrading, we received no php 7.x errors. I copied two blocks of errrors. First is for 5.6 and the second is for 7.2.2. Any thoughts please? Thank you!!! PHP 5.6 errors [Wed Oct 09 12:48:58.753332 2019] [proxy_fcgi:error] [pid 21943:tid 140042491975424] [client 34.231.43.114:34920]…

The errors in your 5.6 log are related to file permissions, specifically on the file /home/radjr1/ojs-data/usageStats/usageEventLogs/usage_events_20191009.log. Check the owner, group, and permission settings for this (and similar files in your files_dir). The warnings in your PHP 7.x log include t…

[image] radjr: PHP 7.x removed a couple of functions that are in 5.x Correct. For example, the old split function is now replaced by the explode function , which works in 5.6.x and 7.x.

Re permission, I set the owner from root to the account user and the errors stopped. Thanks for your help.

Yes, the logs cleaned up nicely. One more weird error though… [Wed Oct 09 17:13:18.169279 2019] [proxy_fcgi:error] [pid 29283:tid 140042416441088] [client 5.8.31.90:39032] AH01071: Got error ‘PHP message: ojs2: 404 Not Found\n’, referer: http://www.wmpllc.org/ojs/index.php/jom/wp-login.php
