Web-Proxy ERROR displayed ....... no Proxy is running at all

in version 3.x even 3.11 we had an annoying error , suddenly an error displayed at the ( hotspot client) browser saying that there is an error to display the page … contact your cache administrator !!!
while there is no proxy running at that hotspot at all !!!
these hotspots are installed in RB333 + RB600 , its linked wirelessly to a main router os , which redirect all port 80 to an external cache server by dst-nat rule ..
after rebooting the hotspot the problem will be fixed , but it may appear at any time later , then rebooting …!!!

Please see the current thread dealing with this issue.

http://forum.mikrotik.com/t/hotspot-redirect-blocked-by-mt-proxy/19962/1

Its caused by the transparent proxy being turned on for hotspots by default; also because the mikrotik proxy doesn’t work properly at the moment.

so … ??

there is no solution yet !!!
10’s of MT users or let’s say 100’s are suffering of the sudden ERROR !!!
what version should we wait ?
its Unacceptable ERROR , 100’s of clients depending on us to provide them the good service , not ERRORS ..
