I'm hoping someone will be able to help me, because I am out of ideas (and everything Google can give me) now.
We've got some courses that are very large (SCORM files) and it's causing backup issues.
Initially, none of them would back up, they'd just sit on "unfinished", meaning none of the following backups would run.
I've updated PHP to 5.6, changed max_execution_time = 3600 in php.ini and turned on "enabletgzbackups".
Some of the smaller ones do now backup, but I'm still having issues with some of the larger ones, where I get "Coding error detected, it must be fixed by a programmer: progress() value out of range".
I've found a few possible solutions, such as: https://tracker.moodle.org/browse/MDL-45783?focusedCommentId=296114&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-296114
but that tells me to modify "moodle\backup\util\core_backup_progress.class.php", but that file does not exist on my 2.8.1 server.
I've even tried searching every .php file within the util folder for the string "TIME_LIMIT" in case it had been moved to another file, but I found nothing! It's really frustrating, because I think this would have fixed my issue.
Has anyone got any suggestions? Thank you!
