Warning: preg_match_all(): Compilation failed: invalid range in character class at offset

Hi Frontend dev here trying my hand at a Roots setup… as per current docs.
Saving WP Bakery pages, triggers the error every time… the page redirects without the page id to /wp/wp-admin/post.php.
This only happens on my local instance and not on the staging environment. I suspect that this may have to do with my vagrant virtual box set up and not WP or Sage itself.

Anyone seen this error before and know how to fix it?

Thanks,

Julie

Hi Julie,

Do you have a stack trace that we can look at? Or what file it comes from?

Also: are you using PHP 7.3 and WordPress pre v5 (e.g. 4.9.8)? I ask because I’ve had a similar issue using those 2 together.

Hi there,

Thanks for replying. I really hope we can sort this out.

Wordpress V 5.03
php on my vagrant box and on the server AWS are the same.

Looking at your stack trace, I don’t see anything that suggests it could be Bedrock related.
Have you tried contacting the support for WP Bakery? Their dedicated support is more likely to be a better choice to resolve the issue.

I did, but they insisted on an environment… It works on staging so not like that would help, since it works there. Oh well maybe I’ll figure it out. Thanks for your help.
