WampServer

I'm having an issue with something quite weird. I executed a script giving an error. Later I removed a dot (.), I executed it again and then it reported again an error message
When I placed the dot back the script worked well.

This is one mistake. Now I have probably the same sort error while there is no error at all. The script runs well but still there is an error code.

What causes these mistakes and how can you solve them? Rebooting?

Is there a sort of cache for errorcodes somewhere that has to be defaulted first?

Hi,

Please answer to: READ BEFORE YOU ASK A QUESTION

WHAT IS THE EXACT error message ?

---------------------------------------------------------------
Documentation Apache - Documentation PHP - Documentation MySQL - Wampserver install files & addons

I dont know the answer, its just as I said. I solved it meanwhile.

Some other thing is that the browser css doesnt seem to be there or only sometimes and then dissappears. What causes that?
