Problem with update and with adding new products

Hello
I have been getting error messages in our shops when:
1) trying to add a new product. Once I save the product the error message shows (see below)
2) when filling up STOCK of a product. Stock is down to 0, I want to fill up 10, then save, same error message
3) also now, when trying to update Joomshopping from 4.18.5 to 4.18.7 the same error message appears.

Need help!

Aw: Problem with update and will adding new products

Hello Support Team
Thank you for coming back.

In the meantime my webmaster was able to do something to the PHP (or something like this...?) that helped solve the problem with adding new stock or new products.

BUT... since then we have another problem namely <code> is showing on the frontpage of the shop. And it is also showing in the PDF invoices. (See images.)

Can you help us remove this?
I will private message you an admin login

For your information: We have 3 shop domains but the error occurs only on https://shop.keysofenoch.eu
This one is the only onw with Joomla version uptodate in version 3.10.8 (The other domains have earlier Joomla versions.)
