Fatal Exception Error caused by incompatability with plugin

Hi Everyone,
A website I’m looking after went down, was using the WP-Ocean theme at the time.
I wasn’t able to access /wp-admin.
The issue turned out to be caused by an incompatible plugin.
So we had to change the theme as it was a problem with an incompatible feature with the theme.
The issue said it was caused by woo commerce but after disabling the single plugin the problem still remained.
I have changed the theme for now but is there a list I can check somewhere with compatible plugins?
Thank you in advance for any assistance.
