Intermittently, pages do not display in the browser and I have no idea why. The code is being sent to the browser (you can see it in 'view source'), but nothing on the screen. It is intermittent - and if I step through the code using a debugger - it never fails . My platform is OS X 10.5.8, FF 3.5.2 (but it fails in all browsers), php 5.3.0, apache 2.2.11 and amember 3.1.8PRO. Refreshing the browser will eventually bring up the page. It almost looks like something is getting messed up with php's output buffers - but it is just a guess. I have never seen this issue before - has anyone else seen this? And what do I do to solve?
What kinds of changes have you made to your templates? Anything in your .htaccess files for gzipping content? Have you tried reverting your templates back to scratch (just to test) to see if the problem persists? Be sure to completely clear your cache.
Although I have altered some of the templates, it is happening the in the amember admin pages as well - and again, in all browsers - with caches cleared.
Just to narrow it down to your client versus your server. Do you see the same problem with the aMember demo here: http://www.amember.com/demo/admin/ (user : demo password : demo) Also, in the root of your aMember folder on your server do you have an error.log file? Anything in it? Drop me an email {my username here @ hotmail.com} along with steps on how to reproduce and a aMember user/pass to test with and I'll see if I can troubleshoot it on this side for you.
