i could not even be able to access the backend in order to deactivate the plugins and themes….the error was still displayed………..
but i tried something that worked….am not sure if it is a temporary solution or i will keep getting the same error after sometime
i turned on worpress debug mode and and inserted this plugin (https://www.ads-software.com/extend/plugins/simple-error-handler/) on my mu-plugins folder……
when i turned off wp debug mode the error was gone……
was this just temporary??? or its ok already
