My site is broken with the Neat template - cannot edit

Permalink Browser Info Environment April 24, 2020 at 7:38 PM

I haven't touched my site for the last year, and now I go to edit it (Concrete 5); and there's some error:

Whoops \ Exception \ ErrorException (E_WARNING)
preg_match(): Compilation failed: invalid range in character class at offset 4

I'm not a programmer, and if I change the theme the site is no longer broken.

What can I do to fix it?

Hi,

so I guess your server updated the PHP version during this last year, probably that's why you're getting this error.

The culprit seems to be the preg_match function. This function is never used in the theme, so I guess it's related to an add-on or some custom development.

I have installed the theme on a fresh install of concrete5 and it's working fine with PHP 7.4

The code you have pasted belongs to PHP Simple HTML DOM Parser, which again has nothing to do with the theme.

Maybe you added some custom PHP code or add-on to one of the theme areas, that's why it's breaking when you activate this theme and not with another theme (themes usually have differently named areas, so they don't show the same contents).

My advice would be to figure out what is using the PHP Simple HTML DOM Parser and disable it. You could also try removing any add-ons or custom code one by one to find out the culprit.

Obviously if you think the theme is the problem, you can switch to another theme if this solves it for you.

Hope this helps,

Thanks for the reply. I didn't even know where to begin, and this will be helpful.
