Is there anyone that could come with a solution to this

Is there anyone that could come with a solution to this problem that has remained unsolved for over two months.

Here is the problem: if I keep the plugins folder in wp-content as "plugins" I get a white screen when clicking on the site URL, whereas my plugins both in the network admin page and in the main site admin page are all working fine.

However,if I change the name of the plugins folder to "plugins1" the site becomes fully visible while both admin pages (for the network and for the main site) show no plugins at all.

hoping that somebody can come up with a solution.

Best Regards!
