Very strange, I have realized that a pair of day ago a website hit the disk limit (5 GB) . After that, the websites using litespeed cache plugin (joomla), are loading very very slow, but finally load and create a cached page because the next load is fast, But if you clear cache (plugin), the pages load very slow again (50 seconds).
In addion, SMPT connections not works, and php mail neither (test email)
I have upgraded to 1.9.1, but same results.
The strange is that the other sites without cache plugin, load prety fine.
Anyone has hit the limit or face a similar issue?
