503 crash on cache options

Hi,

Sure someone else had same problem but can find any solution.

Problem is on two websites.
Host : shared hosting OVH
Last WP & litespeed plugin versions – Php 8.0 (same problem on 8.1)
Report ID : JSOTMRJB

Admin access to admin.php?page=litespeed-cache gives a 503 error. In php logs I can see connection time out. I can’t change php.ini values on this shared host.

All was wordking great until I change config for cache object. It was ON with Memecached but showed a “pass test” error. I changed to redis (installed) and all was ok. I disabled object cache and then 503. Now i can’t get cache page.

Second website :

After object cache change to redis I got a 503 crash. Now all web site (admin and front) is getting 503 error if Listespeedcache plugin is activated.

Not just cache options like on previous site.

How can get rid of this 503 on both sites ?
On first one litespeed seems to works correctly but I need access to cache options.
On second one I need to reset cache options and get access back to all plugin options.

Any idea?

Thanks for your jelp
