FLEXIcontent Category menu item MariaDB error

I have a very simple error.php in my template. I just added:

if ($this->error instanceof JDatabaseExceptionExecuting) {
echo htmlspecialchars($this->error->getQuery(), ENT_QUOTES, 'UTF-8');

and it worked!

Thanks a lot.

Hello

so the error SQL message was shown

but since you have not provided the error message here
it is not by FLEXIcontent code ?

e.g. is the SQL error in some 3rd party content plugin ?

That was it, SEOSimple plugin. It's weird because it works well on the native Joomla menu items. I removed it.

Thanks.

Hello

we trigger content prepare on category description text

- and SEOSimple plugin tries to use variable 'id' without checking if it is set

i have alread made a change for avoiding this error

also i see this plugin has not been update for long time ... since 2015
