Hi

This is the error,

Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /sata2/home/users/qdoors/www/www.qdoors.com.ua/templates/qdoors_new/html/modules.php on line 57

It comes from a file of your template.

More specifically is that code:

call_user_func($styles[$style], $module, $params, $attribs);

Seems like your $styles var is empty.

From log:

[Thu Oct 22 15:51:22 2020] [warn] [client 88.81.226.126] mod_fcgid: stderr: PHP Warning:  call_user_func() expects parameter 1 to be a valid callback, no array or string given in /sata2/home/users/qdoors/www/www.qdoors.com.ua/templates/qdoors_new/html/modules.php on line 57, referer: https://www.qdoors.com.ua/index.php/produktsiya-vm

I can give you administrative rights to the site

Attached template.

This issue is forwarded to the developers. Meanwhile, you can try this:

1) Disable PHP warnings in Joomla. They are not affecting any functionality (if we are talking about warnings, not errors; in your case it is a warning),

2) Try changing that line of code to call_user_func(array($styles[$style], $module, $params, $attribs));
But please make sure you make the backup of the correct file so in case of an error, you could replace that file on the server.

  1. I cannot ignore the error. Due to an error, part of the site's functionality does not work.
  2. I tried to replace the code snippet. It got worse, all modules were no longer displayed.

I can send a backup of the WEB-site, if necessary.

Module "Custom Filters" (https://extensions.joomla.org/extension/custom-filters-pro/) for VirtueMart does not work. When trying to filter a product by the selected parameters, the error mentioned above occurs and the display of the module disappears.
The module works with other templates without problems.

Unfortunately, I can't fix incompatibility with 3rd party plugins.
I will forward this issue to the developers.

Can you recommend a module for filtering products by custom fields that will be compatible with your template?

I have already tried several different product filters from different manufacturers. They all have the same compatibility issue with your templates. The same error is always returned.
I can provide all the necessary access to my WEB-site.
