Hi, I have a website application developed using PHP with RH Linux v6.0 on the server. The slide show on the homepage of the website shows only 4 out of 5 pictures. The fifth (the fourth one in the order, of course) does not show on the site, but only a blank block is shown. The uploading / deleting of the photos is done through an admin module prepared for the users. Tried to upload new photos but of no use.

We have only two users on the Server - root and another application user.

Can somebody please suggest some remedial measures/ areas that need to be looked into to remove this anomaly.

This application was originally on Windows and was recently migrated to Linux environment for operational convenience. Since then encountering this problem.

Needless to say, I am a novice in the area. Thanks in advance.

Welcome to LQ!
What do the logs say?

In addition, fyi 6.0 (if you really mean that) is pretty old. It should be 6.8, which would fix a lot of bugs and security updates.
I recommend you update soon.
(I'm assuming this is really RHEL 6.0, not RH 6.0 which is very old and dead)
BTW, RHEL is a paid for distro ie for support and updates, you need a paid subscription from RedHat.
If you want to do your own support, get Centos, which is pretty much a free rebuild of RHEL; includes updates but not support.

You aren't providing anything, really, as far as details go; telling us "website application" is meaningless...who wrote it? What language? Troubleshooting something on a Tomcat .war application is far different than a PHP, and still different from HTML5. I would look at the code/programs FIRST, because it could very well be (since it came from Windows), that there is something 'windows specific' it's trying to do.

And as others have said about Red Hat, if you're REALLY using RH6 it's ANCIENT, but chances are you mean Red Hat ENTERPRISE 6...which is *STILL* old. Since this is a new machine, you would really be better served by loading the latest versions of things at the start, which would ALSO get you the updated apache web server, etc. And if you don't plan on paying for RHEL, then DO NOT USE IT. You pay for support, patches, bugfixes, and security fixes. Unless you pay, you get NONE OF THOSE. CentOS is 99.x% identical, but totally free. Far better to use it.
