I used to use Piwik for a several webs without problems.
Yesterday I have noticed a problem, when if I go to the page from Firefox, the visit is not recorded, but if I go there (from the same computer at the same time) from Internet Explorer, it is recorded without problem.
Can somebody help me to analyse the problem and solev it?
I use Piwik 1.7.1
Thank you for the help.
