widget don't dispayed on shop single widget area

Hi,

The reason came from these plugins: https://prnt.sc/sfq4pt
When we deactivated these, left sidebar works again. So, pls note that you should install the needed plugins and use one plugin for your purpose.
For example, pls use only one plugin about cache instead of using 2. Both of them may take the conflict.

Pls check again then let me know the result
Regards,
Yame
