Hi @rajkonocko,
When you said “Same after activation plugins back.” you mean that after you re-activate all the plugins, the freezing continues again, or it’s actually ok?
If the freezing continues again after you re-activate all the other plugins, then yes, that is a sure sign that there’s a conflict. In which case, could you please isolate the issue by re-activating the plugins one by one, and then that way we can know the culprit plugin and I can try and repeat on my end. To be perfectly honest with you, the issue is actually likely the fault of the conflict plugin rather then on our plugin. As in, it is likely that this other plugin is perhaps loading a style or script on our plugin settings page and this is causing an issue. So the solution will likely be that the other plugin developer needs to control the scope of their styles and scripts. If this all sounds like too much bother to you, you may want to just deactivate the culprit plugin, do the changes you need to with our plugin, and then re-activate the culprit plugin. As with our plugin, it is a plugin typically used once and is set and forget and doesn’t need to be fiddled with too often.
Thanks,
