Update to Akeeba Backup 7.5.6 breaks two WordPress websites at InMotion Hosting with critical error:
There has been a critical error on this website. Please check your site admin email inbox for instructions.
But a similar website at SiteGround accepts the Akeeba Backup without problems.
Two websites at InMotion Hosting but website at SiteGround (SiteTools) doesn't have the problem. I'll describe the problem for the two websites under development at InMotion Hosting (penny.mattsson.pro using Spacious theme and avion.mattsson.pro using Astra theme). For avion.mattsson.pro, I think WordPress was already up to date but a few plugins were out of date, including Akeeba Backup. Right after the Akeeba backup finished, clicking on any other link went to a white screen displaying the critical error.
On penny.mattsson.pro, this same error message appeared after updating Akeeba backup AND a few more plugins. The penny.mattsson.pro site MIGHT have other problems -- the theme won't update, and removing unused plugins seems to never finish, for example.
In both cases, InMotion Hosting tech support identified the problem as being caused by Akeeba Backup plugin. If we renamed the plugin folder over FTP, then we can manage the website again. He reported two error messages shown by Akeeba backup for penny.mattsson.pro (I don't know where he saw the errors, as I think the website was having the critical error at the time)
Error: Callable "Akeeba\\WPCLI\\Command\\NamespaceDescription" does not exist, and cannot be registered as `wp akeeba`.
Akeeba Backup for WordPress requires PHP 7.2.0 or later but your server only has PHP 7.1.33.
At the time "site health" info was showing the PHP version as 7.4.16.
The tech said the server was properly configured.
Since there are a couple ofother errors that I must consistently work around at InMotion Hosting but not at SiteGround, I found a similar WordPress website I'm hosting at SiteGround (teal.elizahost.com using Spacious Pro theme) that needed plugin updates. I updated WordPress and all plugins except for Akeeba Backup then checked over the website. THEN I updated Akeeba Backup and the site was STILL fine.
So the problem seems to only be happening for me at InMotion Hosting websites.
Still, I have a lot of practice and staging websites hosted at InMotion Hosting, with years of successful plugin updates to Akeeba backup, so I hope you can help me to solve this problem.
