Hi Denisha,
can you please check your PHP memory limit? That might be the issue?

Also if you could provide your JEvents Support Info, it could be of help.

Im on hold now with GD to resolve the tip: Your php setting for max_input_vars may be too low (currently it is 1000) - if you have problems updating your configuration options then please ask your webhost to update this setting to 2000

Added the following to the ini file, same 500 Internal error message.

max_input_vars = 999999
memory_limit = 512M
post_max_size = 192M
file_uploads = On
upload_max_filesize = 192M
max_execution_time = 600

are you still seeing the max_input_vars message?

If you'd like me to take a look at your server - please send me login details via PM.

Problem was a cache with too many files in it .

Wow, Thanks! What should I do to prevent this in the future?
