Polylang in/compatibility

@drachires ,

Could you please try to create a test product using ‘WooCommerce > Products’ and then try to reproduce the Smart Manager plugin issue using the same and do let me know your views.

As the issue seems specific to your site, we’ll need to isolate what’s really causing this problem. Here’s something that will help:

• Install a free theme like Twenty Twenty or Storefront but do not activate/switch your current theme
• Install the free plugin Health Check & Troubleshooting
  on your site – this plugin is developed by the www.remarpro.com team and is pretty good at diagnosing problems in such situations.
• Once the health check plugin is installed, keep only WooCommerce, Smart Manager and Polylang plugins active for the admin side and try to reproduce the issue you reported. Make sure to do this only for the admin side – that way visitors to your site won’t be affected.
• Here’s a nice article that explains this process.
• If the issue does not occur, it means the problem is with some other plugin. You may try activating/deactivating a combination of plugins to figure out exactly what causes the problem`

Do try the above steps and let us know your views.

Honestly now I am not 100% sure if it is polylang issue because I am experienced with finding the plugin that is causing the issues … and I tried everything you explained to me before I messaged here … but the thing is, that this issue is really weird, what I never experienced, that sometimes the issue appears, then disappears for a while and then appears again … but I found that in console is this issue:

it looks like more the javascript issue than the php issue but maybe you can find out more

Now i installed WP OPcache and flushing the OPcache helped, curious if for good or just for a while

No it did not … I am still seeing this error:

and I see only first product but others like they dont want to load …

what is really weird because it fixes itself sometimes randomly but then it appears again … I never experienced such issue

@drachires

Thank you for the JavaScript error message.

Would like to update you that we have done some fixes and improvements in the code and released a new update for the Smart Manager plugin [i.e. v6.1.1].

Could you please update to the latest version and then have a check and let me know your views.
