Hi, I am getting the following error message when updating my BeTheme to the latest version. Any reason as to why and how I can fix the issue? Thank you!

    Hello,
    Is your PHP version 7 or higher?
    Also, is your WP up to date?
    Thanks

    Hi,

    My php version is at least about version 7 and yes, WordPress is up to date.
  • PabloPablo
    Can you reinstall BeTheme completely? I mean, remove the BeTheme from themes directory and install the new one from "themeforest" package.
    Do not be worry about the content, it's all stored in the database - but in case, please create a backup.
    Thanks

    Please update your theme to the latest version and check, if your php version is 7 or higher.
    Please provide us with your hosting environment settings, to do that please follow these steps:
    1) Go to the Wordpress > Tools > Site Health http://prntscr.com/nlyb22
    2) Click at the “Info” on the top of the page and open the “Server” tab http://prntscr.com/nlybm2
    3) Take a screenshot of the content inside that ‘Server’ tab http://prntscr.com/nlybyr
    Please make sure you are using Wordpress 5.2 or later, previous versions did not have this option built in.

    Please use snag.gy or pasteboard.co to host the screenshot and send us the link to it.

    Thanks

    I have just reinstalled the theme and it did not solve anything. Please advise. Thank you.
  • PabloPablo
    lbereck,
    Please send us WordPress dashboard access privately thru the contact
    form which is on the right side at
    http://themeforest.net/user/muffingroup#contact and we will check what
    might be the reason.

    Notice!
    Please attach a link to this forum discussion.

    Thanks

    Did you check if your theme is up to date?
    Also, please disable all of the plugins, clear the cache of your browser and try to create new page, check if it works.
    Thanks

  • PabloPablo
    Can you create another topic? I'll ask you for login credentials - I ask you for this because it will be easier to understand which website was yours and which the lbereck website.
    Thanks

    Dashboard access will not work because you can't even access /wp-admin. Every single page displays that error message no matter if you were logged in or not. What can we do to fix this?
  • PabloPablo
    Can you re-install BeTheme? You will not lose your content because it's stored in the database.
    Simply remove the BeTheme folder (FTP) from themes and install new package from the Themeforest.

    Thanks

    I have already reinstalled a new version of BeTheme directly from Themeforest.
  • PabloPablo
    Is your PHP Version 7 or higher? It looks like it does not recognize the function, which could be not working for older versions of php.
    Also, can you remove your child theme? Copy it to your local device, but please remove it from the server for a testing purposes.
    Thanks
