I use prestashop 1.6.0.8 . One year I had no problems, but befor a few days  I found out that my castomers can not confirm theyr orders. ERROR 500 is written on the page.  

I hope YOU can help me solve this problem.

it could be some changes on your server, or something you changes in your store.

 

please try to enable debug mode and then try again with rest order, you should see more detailed error message.

 

set _PS_MODDE_DEV_ to true in file /config/config.inc.php

I made what you advised me. Here is the result

it seems related cache files. there are too many files. And it seems related to corssselling module.

You may try to clear Smarty cache to see it fixes your problem, or maybe you can try to disable crossselling module to see if it fixes the issues.

thank you!

Just noticed a typo in my message by missing a word, "You may try to clear Smarty to see it fixes your problem" should be "You may try to clear Smarty cache to see it fixes your problem". to avoid confusing, I have corrected the original message too.
