thanks for the respond :)
the setting in customize i already tried.. didnt worked.
yes if i dont get any fix i think i will switch to a older version, if i get a solution i gonna post it here!
hey it seems you changed your site url but the website is still trying to access things on the old url
please refer to this

i think you need to do "Step 2 ā Update the remaining URLs"
