[testingprem]

Hi,

We have installed Testlink 1.7 in our server. when more than 2 users are trying access Testlink 1.7 from server we are getting a "page cannot be displayed error" pls let me know whether there are any restrictions for number of users to access Test link 1.7 simultaneously from server.
