after the upgrade OpenLiteSpeed to 1.5.10, the cache.so module disappeared?
cannot find external module: /usr/local/lsws/modules/cache.so
I have same issue, only cache.def there… And my cache is not working
As above, it is moved to server core.
But there is bug in WebAdmin which will be fixed in the next release. Right now, if you get that issue, you can make a fake cache.so in that location, just in case you want to change the setting of it in webAdmin.
