Cron setting On problem

First of all thanks for your time and support!

I just put on in this;

https://docs.litespeedtech.com/lscache/lscwp/crawler/#general-settings-tab

Yes I have wordpress in one sub dir so I have the two .htaccess
And in the two are info about litecache

I press On and give me error 404, modify the root / htaccess abd I think that is the problem,

What I want to make is refresh if is possible the cache and UCSS every week for example, that is possible? for no delete manual and lost all the performance of the cache and work with UCSS

That crawl say that can modify the htaccess in the setting, at least in spanish.
I trie to replicate the error, but no can, I think was one hosting problem, because I also has problem for upload files, I no can replicate the error so I mark as resolved question.

How I can request one feature? When I put this in my htaccess the web load very fast in mobile and in PC 100 – 95 score

If you can make this automatic for each post, and if the UCSS inline is processed no use the preload, will be great. Jut use the preload if no is processed.

One box with preload UCSS for on – off
And one box JS preload for put the url one by line for critical JS
And one preconnect for youtube, google etc for example if the post have youtube, that can be automatic.
