    This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty theme. If the problem goes away, enable them one by one to identify the source of the problem.

    If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.

    Hi James
    Thank you for your advise. Plugins I have Classic Editor, WPBakery and SG Optimiser (for HTTPS) and Contact forms. I deactivated them one by one and also tried changing the Theme to Default however I continue to get the same Error on the posts and pages.

    I will try Installing Health Check plugin, if that solves the problem

    thanks

    So, with all plugins off, you’re still getting an error mentioning this “js_composer” plugin? That doesn’t seem possible.

    Yes, i still get the same.
    Im not able to share screenshot here.
    However if you visit one of my pages on the site, for example https://ilandedhere.com/austria/
    and scroll right down before the posts, you will see the error even appearing on the site

    php 7.3 escape the hyphen in a character class ??

    WPBakery Page Builder ask for support https://wpbakery.com/features/support/ if this adds the js_composer plugin with this error Warning: preg_match_all(): Compilation failed: invalid range in character class at offset 11 in /home/ilandedh/public_html/wp-content/plugins/js_composer/include/autoload/hook-vc-grid.php on line 163 or temporarily use php lower than 7.3
