Hi Jerry,
This sometimes happens when there is so much data in the error log that PHP runs out of memory trying to load it.
Can you try &perPage=1 on the end of the URL and see if that works?
If so try larger and larger numbers until you find the limit and try and erase some of the records (if you don't need them).
Let me know what happens.
Thanks!
