Dear All, I'm experiencing such a problem with Uniserver. Tried on two different computers, one with Windows Vista Business 32bit, the other - Windows 7 (unfortunately did not check exact version). The situation is as follows: On Vista machine I've unzipped Uniserver 5.6.3 succesfully, copied my CakePHP site into it, imported data to local MySQL and everything worked fine. Than I copied everything on my pendrive - and still everything was OK. Than I put the pendrive into win 7 machine and I could not open any script using database: either my Cake site or phpmyadmin - I always got http error 500 (BTW - I cant get php to write what is the exact error. I turned apache into log mode debug and set up a log file in php.ini and have nothing meaningful in apache log and nothing at all in php log file). MySQL was working for sure (tried query browser) and in addition - I also could not connect to remote database server (which also was working and is tested to accept remote connections). After running it again on vista I had the same problem (but nothing was changed). And now comes the most weird part: After installing WAMP, turning it on an than off - all started working on win 7 (both phpmyadmin and my cake site). On my vista machine the situation was a little worse: after installing and turning off WAMP phpmyadmin works but my cake app still gives 500. I downloaded two different versions of Uniform Server (5.4 and 5.5) with exact same effect. Does anyone have any idea what is the key? Thanks and best regards, podles
