I was trying Snapshot but it keeps stalling at the plugins directory at 84% with no errors. We have tried a conflict test and maxed out all server configurations (1024M memory limit and 3000 max_execution_time) and with all other plugins disabled, it still stalls at the same position. Snapshot log didn't reveal any useful information. Debug log showed this at the end -
Undefined index: interval-offset in /home/********inc/***.nz/wp-content/plugins/snapshot/views/snapshots/snapshot.php on line 908
However, not sure why it is showing up as all plugins are deactivated and file permissions are also okay, I've opened a ticket with my host to check if they have restricted access to it for some reason and I'll update the answer here.
