We get intermittent Error 500 Internal Server Errors in our Joomla / Virtuemart.
It happens mostly in the administrator backend, but also occassionly in the front end.
It happens mostly when performing a search e.g. search for a particular product. But it can also happen by just clicking any link.
See example of error below:
Error 500 Internal Server Error
Your browser sent a request that this server could not understand:
/administrator/[url removed, login to view]
The request could not be understood by the server due to malformed syntax. The client should not repeat the request without modifications.
NB - Please NOTE:
It is important that should you make any chances / Repair / Optimise the database that you first perform a backup. It has happened before where a repair on a table / database caused us to loose 1000's of products and categories.
If this happens we need to be able to determine which products / categories are missing so that we can add them again. You will need to assist with a query or some mechanism to quickly pull a list of missing products / categories (Product Name, Product SKU and related categories.)
