A lot of errors are being received after latest WP 5.4 Upgrade

edited April 2020 in Theme support
Each time I wish to update a previously created page, I receive all this errors, which seems to be related to BeTheme's functions. The page I try to edit is not updated when this errors do appear.

I am also using the latest Theme Versión: 21.5.9.3

I would appreciate a lof if you guide me to fix this. Thanks in advance.

P.S. Please note I am masking the home folder and the subfolder inside public_html as they may be sensible information. If you need it please tell me how to send it in private.

    thanks
  • Pablo. Thanks for answering

    1) Please check if your BeTheme is up to date

    As I mentiioned in my topic, my current version is the one you say it should be. 21.5.9.3

    2) Please check, if your PHP Version is 7 or higher.

    I am using PHP 7.1

    3) You should check, if after disabling all of the plugins, clearing the cache this issue still apear.

    I yet need time to check this. I will come back later, just after disabling all the plugins, nevertheless I needed to ask:

    Should I also disable all the plugins which came bundled with the theme?

    Thanks for your patience.

    Hello,
    not really, because the bundled plugins never cause any issues, those are always the ones that users install additionally. Please disable them as they are the main cause of issues.
    thanks
  • Hello there,

    I am not able to do this at the moment because of the affected page is being used as a way to inform to the citizens about the current pandemic situation in the municipality.

    I would appreciate a lot if you allow me to keep this question open in order to continue when we are able to do the investigation and changes.

    Thanks in advance.
  • Sure - we are waiting for your response.
    Thanks
