I started upgrading the System version to 4.7.11, initially its stuck at Upgrade step.

 

Hence I tried installing manually by downloading the software and uploaded after extracting.

 

Now admin/upgrade started the upgrade, but its been stuck and our site is down from more than 4-5 hours.

@Marc Stridgen @Adlago Any help here?

 

Its almost similar to what happened here , but this time still its not moving forward.

 

@Afrodude Any help here would be appreciate

@Marc Stridgen For your attention, appreciate any guidance.

I would recommend checking your servers PHP error log first, see if that has anything relevant

@Stuart Silvester Sure, log location please?

You need to contact your hosting company and ask that they increase your memory limit, as its being hit at present and causing you those issues

@Marc Stridgen We will surely do that once the service is back online.

Do you think that is the reason for the current upgrade failure as well?
Because we have observed similar errors since around Dec 2020. So, we doubt that as blocker for the current upgrade error.

Yes, its very likely this is the case

The issue is successfully resolved by @Afrodude 

After upgrading the PHP to 8.1 and increasing the memory, the upgrade was successful.

We are really thankful for your help and advice again!!

Glad to hear that sorted the issue. Looking at your logs, it looks like you could have done with that for a while, so may serve you better going forward
