[Plugin: An Unexpected error] Unable to Install Plugin – WP server error?

Hi there,

I’m currently experiencing this error on WP plugins. I cant search and install new plugins unless I download them on WP plugin directory and manually install them. There’s a plugin where I need to install automatically but when I tried to do it manually it doesnt work properly as I need to edit the root of the theme.

Kindly please check and let me know if we can do something about this? My other websites are working properly so I dont know what’s wrong with this one.

Please check this link
Another error occurred when I tried to install new plugin.
Click here to check pls. Thanks 🙂
