Website backend is slow + error-log tells "enfold/framework" cannot be served

Dear all,

my website backend is extremely slow since yesterday.

Today I tried to add a new page to the main-menu, but after clicking the save-button the server returnes a error 500 after a certain time.

Error-log tells: Cannot serve directory /…/wp-content/themes/enfold/framework/: No matching DirectoryIndex (index.html,index.htm,index.shtml,index.php,index.php3,index.php4,index.php5,index.phtml,index.pl,index.cgi,index.wml) found, and server-generated directory index forbidden by Options directive ( I am not sure if this is connected with the above issue)

Edit: A new error appeared in error-log after I tried to save the menu-changes (I added a page):
End of script output before headers: nav-menus.php, referer http://eperi.de/eperi/wp-admin/nav-menus.php?action=edit&menu=130 (I guess this error was caused by saving menu-changes this morning and receiving this 500 script-failure)

I also checked if there is a new PHP-Version available in hosting-menu and found that right now I use 5-54 STABLE (5.4.30). I could switch to 5.56 STABLE (5.6.2) if you think this is worth a try.

I already asked hosting to increase php-memory-limit and to enalbe increase of “max_input_vars” to 2000, because standard-value (1000) might be a possible cause for the slow backend and the problem that I cannot save menu-changes anymore.

I found this closed thread with the same topic (https://kriesi.at/support/topic/website-is-extremely-slow-when-navigating-from-page-to-page/), but cannot se what the solution might be due to private answers.

Do you have any clue what might be causing this issue or what else I might try? Since I must admit – as always :D – I did not change anything.

Edit: Hosting replied the memory-limit is set to maximum (100MB) now. I tried to add the menu-item in my main menu, again. But sadly, after a while it appears a 500 Scripterror.

The main menu holds 48 items for each language. I read about this max_input_vars limit/problem which might be the cause.
So I tested to edit and save an other menu with only 5 items. And et voila, inside this other menu with less items inside, it instanty saves my changes.

I am not sure what to do to solve this, but maybe I am one step closer to a solution to be able to change and save the main-menu.
