I am in the process of moving to a newer server, but I am getting a 500 page error due to redis being enabled.

My host is handling the migration but I have no idea how to resolve this issue, I had a old contraints.php file saved with Redis turned off but switching file names around has no effect. I'm a little fish in a massive pool and I have no clue.

Turn off Redis usage on the source site, via the ACP and make the provided changes to the constants.php; move database and content to the new server.

Are you certain it's Redis? What is the error you are seeing?

If you've completely removed or renamed constants.php, then it should no longer try and connect to Redis.

This is the Redis error, I think I need to try to connect with FTP.

This is another error thrown for another site, it only shows via the ACP which logs in as a guest without a login box ever coming up.

That last error is the result of a custom plugin it looks like. You could try renaming /plugins/hooks.php temporarily to see if this allows you access to the AdminCP.

This is driving me mad, I don't know how you good folks manage to do it for a living (even with your level of knowledge).

I managed to disabled all the plugins, then boom a new error. lol

The first site is fine since disababling Redit.

Thank you so much for everyone's help so far. ❤

What version of PHP is running on the new server?
What version of IPS are you using?

Edited February 17, 20214 yr by Nathan Explosion

v4.1.12.2 (very outdated).

The multiphp is set to 7.2 which I don't think is compatible. I'll have a look in putting the right PHP version in place so that it works. Thank you @Nathan Explosion

There is the information that is always helpful 😄

Yep, work back to an older version...I can't be 100% sure but I think 7.1 is the highest that you can use, as IPS 4.3 introduced support for PHP 7.2

Actually, you may need to go to PHP 7.0 as PHP 7.1 support came in fully with 4.1.18

 

Thanks, I checked on the live set via cPanel to see what version it was running.

It's 5.6, will wait to mess around with this further until I can upgrade to the latest version. At least for now, it's ready. Thanks again!
