Can you please take a screenshot or send us the error message?
We have tested the current version of the Point of Sale plugin 2.2.1 with WooCommerce version 3.8.0 and WordPress version 4.6. No issues or crashes occurred and the Point of Sale plugin version 2.2.1 is compatible with the latest versions of WooCommerce and WordPress.
I have the same problem.
The error message is: “There has been a critical error on this website”
POS plugin version 2.2.2
WooCommerce version 5.3.0
WP crashes as soon as both plugins are activated. Activation of just POS plugin without WooCommerce doesn’t crash
We just performed compatibility testing with WordPress 5.7.2, WooCommerce 5.3.0 and BizSwoop POS 2.2.2, as you can see in this video, no errors or crashes occurred: https://www.loom.com/share/ad9760aed603421aba26579863bc7c77
We suspect another plugin could be causing a conflict with the POS plugin, creating this crash on your configuration. Can you please perform plugin conflict testing? It’s easy, deactivate all plugins except WooCommerce. Now activate the POS plugin, does the crash still occur? If yes, please send us the crash log to review.
IF no crash occurs, one-by-one activate a plugin until the crash occurs again to identify which plugin is causing the crash behavior.
I have followed your advice:
1) deactivated all plugins
2) activated WooCommerce 5.3.0
3) activated POS 2.2.2
