    I am updating my WP core and plugins on a local staging site.
    The site i need to update was not updated regularly and I therefore have an old configuration of WP (5.1.8), Apache (2.2), PHP (5.3.13) and many plugins will also require updates. Therefore I will proceed in steps.
    I Will only discuss here the update of a plug-in which broke my staging site.

    Configuration tested:
    MetaSlider : 3.24.0 (updated from 3.10.2)
    WordPress core: 5.1.12
    Apache: 2.2
    PHP: 5.3.13`
    Step 1:

    Successfully updated core WP 5.1.8 -> 5.1.12
    Successfully activated and updated plug-in MetaSLider 3.10.2 -> 3.24.0 from back-end
    However Front end AND back end broken after update of plug in.
    Errors displayed in browser are also saved in apache log file:

    Can I fix this by delete the meta slider sub dir in the plug-in map of wp-Content? and update the database manually, or is that a bad idea? What would you recommend? I no longer can access wp-admin.

    temporarily rename the folder containing MetaSlider in your file manager area or ftp client tool.
    renaming a plugin’s folder will deactivate the plugin
    if the plugin is the source of the problem, then you should be able to login to WP-Admin for further troubleshooting and investigating.

    Hi

    The error is related to the code using syntax from PHP 5.4 so if you upgrade your PHP version then MetaSlider will function. I will patch that file though to use the older syntax. Thanks for reporting.

    You’re also ok to delete the MetaSlider (ml-slider) as we don’t do anything destructive. You can just reinstall it after u update your PHP version.
