Problem
On Google Analytics, sometimes this error comes up.
“Internal error. Please try again later.
Analytics has encountered an unexpected condition and cannot fulfil your request.”
What to do when this happened?
Solution 1 Disable adblock
As mentioned in this forum, disabling adblock works for many users
Solution 2 Use another browser
Sometimes disabling adlbock may not work, rather you have to uninstall it. Well, just use another browser such as Firefox then.
