It seems this is related to the pro/premium version of the WordPress Download Manager plugin.

Please contact the plugin’s vendor for direct support, as commercial products are not supported here at WordPress.org.

Good luck!

Hi George,
do you mean becouse WordPress Download Manager mage error?

Yes. But it’s probably the premium or pro version if you have it.

You can rename or delete the plugin’s folder to confirm this. Doing so will disable the plain, and if it’s indeed the culprit, restore your website (but without the plugin’s functionality.)

Hoster has php7.4 changed to php 8, that was problem….but yeah i delete all plugins what im not using. Thanks anyway your help as well!
Cheers
