Problem detected in Pigdom Tool

Hello, Igor! I see that the plug-in is not being used now, but the problems are the same. Most of them concern the minimization and caching of files on other services. My plugin does not affect this part. The same applies to the minimization and caching of template files and other plug-ins.
Problems with the blocking of resources can be associated with a limitation in some countries. For example, in Ukraine these resources are not available. Maybe in some countries a similar situation. Although the statistics for this plugin works perfectly for the following countries (RU, NL, IE, GB, FR, TR, US, DE, MD, BY, KZ, LT, EE, TJ, BG, LV, CZ, KG, CA, AU, LU, HK, HU, PT, PL, UZ, CY, VN, BZ, DK, CH, SG, IT)

Unfortunately, if the problem with the Yandex metric is not solved – maybe it’s worth using another service – google analytics? Although any scripts that are not on your site – can not be optimized.

According to the general optimization of the site, you can try the appropriate plug-ins:
https://wordpress.org/plugins/wp-super-cache/
or
https://wordpress.org/plugins/w3-total-cache/

And for if hosting allows you to use additional Apache modules, you can add a .htaccess file to the www or html directory
