  • These errors are all related to plugins (or certain functions thereof) that are no longer supported in the new version you have upgraded to.

    A suggestion would be to de-activate all your plugins & check them 1 by 1 (by re-activating) & see what works & what causes problems.

    Many of these however you will need to replace with something else.

    Hi Gunduzi,

    I have disabled all plugins but still have the same errors.

    What do you think are my options? I can’t really change themes as this was custom done (terribly) by another person.

    Luckily enough the site still works to the public, just a quick flash of errors..

    Seems strange that disabling the plugins does not work

    Could I follow a tutorial like the below:

    Or is this for similar versions, rather than the massive change from 3 to 2?
