Hello,
When I want to display the visitors log to certain sites, I have the following error:
Oops … There was a problem processing the request. Maybe the server had a temporary problem, or maybe you asked for a report with too much data. Try Again. If this error recurs, please contact your Matomo administrator for assistance.
When I select certain days, it works. And for other sites, all the dates work.
I increased the memory values in php.ini and in my.cnf, but the error is still present.
Any ideas?
