internal server error

Hi,

i get this error very often when editing pages/products and stuff.

“Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at support@one.com to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.”

The webhost has done some investigations and says the server is fine, its the theme not working well and cause server crash.

Do you have any solution for me because i cant do much editing before the server crash and the only solution im left with is change theme.

Could you please check what the issue is?

Best regards
P
