Hi,
Thank you for your query.
1. WCPT Lite and WCPT PRO have both been tested with WooCommerce 4.5.2 and have no known issues with this latest version of WooCommerce. You can check this for yourself by disabling all other plugins on your site except WooCommerce and WCPT Lite. You will find them to be working well together.
2. If there is an incompatibility issue between WCPT and a ‘limit login’ plugin then I will be happy to look into it for you. However, there are several ‘limit login’ plugins available and it is not very clear which one you are referring to. No issues are coming up when I am testing with different limit login plugins so please clarify the exact plugin you are using so that I may test with that one.
While I look forward to helping you with any compatibility issues, I need to be able to reproduce the error at my end as well in order to help fix it. If the error does not occur elsewhere except your site, it could be a mix of specific circumstances (plugins / theme / settings) which would require testing directly on your site or a test duplicate site where the error can be replicated.
In that we can continue the communication directly via the plugin website support page.
Regards,
Kartik
