500 internal server error

Hi,

Firstly thanks for this plugin, so straightforward to setup! Got the test product purchased and refunded fine. Only since when I go to either update or edit a product I’ve been having an ongoing frustrating server error. It seems unrepairable and to restore the site to try again I have to create a new database and import my backup. I did get this once before I installed this plugin though a while back, so it might not be related I’d just like to rule it out!

Could you possibly shed some light on what this means from my error log?!

Once the error happens there is nothing I can do, it seems the database is not recoverable. Tried changing the name of the plugins folder, and each time I try dropping the database tables to import the backup sql file but nothing works. I have to create another database and import the backup which restores the site. I can then purchase products, even click around in woocommmerce in the back end until I try updating a product which does the same all over again!

Thanks in advance
