Escape sequence invalid in character class – visual editor problem

By philosofen, 4 years ago. Last reply by Andrew Misplon, 4 years ago.

Hello,
I recently installed the Siteorigin CSS plugin for wordpress.

When I want to use the visual editor it gives me an error at the top:

“Warning: preg_replace(): Compilation failed: escape sequence is invalid in charaacter class at offset 4 in /home/xyz/domains/xyz.com/public_html/wp-content/plugins/so-css/so-css.php on line 756”

Is this something I need to fix/ worry about? If so, how do I solve it. I have exactly 2 hours of experience with CSS, so this is slightly over my level of expertise =)

Thanks
