Hello,
Do you get an error 500 only on the Content Statistics section inside the administrator area?

I assume that you have changed your Joomla configuration.php with the new hosting parameters.

There's no specific requirements on the server for CS to run.

if you want, send me joomla admin access at support@ joomlathat.com and I'll take a look

I was able to fix it in my php.ini. I already had a high memory_limit but I raised several other items and it is good now. I think the main problem was I had almost 500,000 records in database table.

I added these:

max_input_time = 180
max_execution_time = 180
max_input_vars = 1500 (this one had to be changed to make Alter Reports work, so unsure if it made a different with ContentStats)
max_allowed_packet = 8M
read_buffer_size = 512

ok, thanks for the feedback.

well, 500,000 records is indeed a big number. To avoid issues in this cases, we always suggest to clear very old items that you may not need..

Unfortunately client wants them all in there...
