Limited Support
Our team is currently on holiday, so support will be limited during this period. Response times may be slower than usual, and some inquiries may be delayed.
We appreciate your patience and understanding, and we’ll resume our usual support by the end of August.
First of all thank you for adding the Q&A schema in wpForo, a nice update. However, in some questions an error is recognized. I attach an image to make it clear.
Hi @xfok,
This is not a bug. I think you have some specific content in the post which has crashed the JS syntax. I'd recommend check other topics, and please report the errors in English.
Yes, in questions where Latex is used (mathematical writing) it is not recognized. The error reported is the following: Empty escape sequence in string
It is possible to somehow reach this error, being a mathematics site on 6000 questions about 4000 make use of Latex so most of them will not be validated by the Q&A scheme
@xfok ,
Ok, then we can filter that, there is a filter hook on the scheme which can help us. Please leave a direct link to that topic, so I can suggest you a fixing hook code.
As far as I see we just need to remove the backslashes or escape them with new backslashes from the body of question scheme in this case the JSON parsing will work and there will not be any error on validation. So just leave a URL to that topic, so we could see the syntax issues.
@xfok All i see in the above are errors from peepso-groups
Uncaught TypeError: t.group is undefined

All is clear, the Latex raw content has some back-slashes, and they crash the JSON syntax. The content should be filtered. Please let me know which Latex plugin do you use: https://wordpress.org/plugins/tags/latex/
Ok, thank you, @xfok,
This hook code should fix the issue. Please put this code in the functions.php file of your current active WordPress theme, delete all caches and check it again:
add_filter('wpforo_seo_meta_tags', 'wpforo_latext_filter_for_seo_tags');
function wpforo_latext_filter_for_seo_tags( $content ){
$pth = array( '|\$\$|', '|\$(\p{L})|u', '|(\p{L})\$|u', '|\\\text\{([^\}]+)\}|', '|\}\$|', '|\$\\\|', '|\\\pm|', '|\\\times|', '|\\\div|', '|\\\mathrm\{~?(\w{1,3})\}|', '|\\\Rightarrow|', '|\\\Leftarrow|', '|\\\cdot|', '|\\\right\)|', '|\\\left\(|', '|=\$\$=|', '|\\\(\p{L}+)\s?|', '|\\\|' );
$rep = array( ' ', '$1', '$1', ' $1 ', '}', '\\', '+/-', 'x', '/', '$1', '=>', '<=', '.', ')', '(', ' = ', ' $1 ', '' );
$content_fixed = preg_replace($pth, $rep, $content);
if( $content_fixed ) return $content_fixed;
return $content;
}
