Hi, I can't understand when and when but from few days ago I have a big problem with theme and woocommerce appointments plugin. At the beginner everythings work fine. Now when a customer  try to book a lesson the site redirect him to home page with no booking actions. I tried to reserve from back end and I get back this error: <b style="color: #000000; font-family: Times; font-size: medium;">Fatal error</b><span style="color: #000000; font-family: Times; font-size: medium;">: Call to a member function add_to_cart() on null in </span><b style="color: #000000; font-family: Times; font-size: medium;">/home/cantaf5/staging/2/wp-content/plugins/woocommerce/includes/class-wc-form-handler.php</b><span style="color: #000000; font-family: Times; font-size: medium;"> on line </span><b style="color: #000000; font-family: Times; font-size: medium;">746</b> So I tried to do that:

• check plugin udate
• deactivate all plugin
• change setup in all possible solution
• change themes

All this problem disappear when I set another theme. Please can you help me to resolve this problem? thank you Alessandra

This is a very very rare issue, infact this is the first time someone has reported this. Also note that the error is displayed in the core file of WooCommerce plugin which indicates the possibility that the woocommerce plugin might be corrupt or some files unreadable. Suggestions to fix :  1. Go to WP admin - Plugins, deactivate and delete the WooCommerce plugin. To remove it via FTP, simply go to wp-content/plugins folder and remove the folder. 2. Re-install the WooCommerce plugin from WP Admin - Plugins area. 3. Optimise your database, try installing this plugin : https://wordpress.org/plugins/wp-optimize/ and optimise your database. ----

Ok! after a lot of test I found where the problem was: If you enable "show woocommerce profile" in LMS setup some plugin that use woocommerce can't access to it any more. When I deselected this option all works fine. Now ... there is a way to show customers woocommerce profile on them personal area? Thanks roberto

We are also having the same issue with WooCommerce Bookings.  I can confirm that musicale's solutions works but we would prefer to have this WPLMS feature checked. Any updates on this?   Thanks, Lawrence
