Hello.
There is a problem with the shopping cart. After filling in all the fields and selecting the delivery and payment method, the next “place order” operation does not complete, the page begins to refresh. At the same time, the load on the mysql server increases and the server goes down. The problem is in the default and custom cart. Please tell me where to look for the problem?
The store has been open for some time and there have been no problems before.
