Osclass 4.1.0 what ?!

Has anyone tried this yet ? - https://osclass.market/item/download-osclass-evolution-472918

I see that there is no unity of osclass users, everyone are doing their own versions, all with problems and we just cant figure …what to installl… If someone have some experience with this 4.1.0 please share before I do misstake again… Last time i upgraded with 3.9.0 from 3.8.0 website starting giving 500 errors after ad post, and then all ads dissapeared from google search with error in Google Search - URL not accessable" . I downgraded, but the problems are still here. I am wondering if it worth this 4.1.0 …otherwise I will do just clean 3.8.0 with original repo from original osclass github and all from the begginning…
