    I tried to upgrade my php to 7.3 from 5.6.4 and I got a error that said this website had a critical error and my screen shrank when viewing it on desktop. I used a php compatibility checker plugin to see if I can figure out what’s causing the issue. It gave me this error:

    3 | ERROR | ‘string’ is a reserved keyword as of PHP version 7.0 and should not be used to name a class, interface or trait or as part of a namespace (T_NAMESPACE)

    I’m not very techy and don’t know if this has anything to do with me having issue upgrading. Could you shed some light on this?

    This is a false positive by the PHP Compatibility Checker plugin.

    Before you upgrade PHP:

    • Do a full backup, site files and database. The webhost usually has tools in their control panel to do this for you.
    • Ensure WP is updated to latest.
    • Ensure plugins are up to date.
    • Ensure theme is up to date.
    • Deactivate all plugins.
    • Switch to default theme ( One of the Twenty Twenty themes ).
    • Update PHP. PHP 7.4.x or 8.0.x
    • The site should still load fine. At this point.
    • Activate the theme.
    • Activate the plugins on at a time.
    • If you receive a fatal error after activating a plugin, the last plugin activated is the cause of the error.
    • If a fatal error does occur, WP can enter Recovery Mode.
    • One in Recovery Mode, deactivate the plugin the last plugin active and exit Recovery Mode.
    • Repeat the process until the site runs normally.

    I hope this helps!
