I have an issue whereby galleries are not displaying on certain pages.  Problem began after  checking website with RSFirewall and manually correcting permissions. Plugin has been reinstalled, but no change.

Folder and file permissions are set at 755 and 644 respectively.

Thanks,
Desw

Could you provide a link to your site?

I just visited your site and I saw all galleries with no problem. Could you provide a link to a gallery that doesn't work for you?

www.foxrockpaving.ie/ (code inserted with nothing showing)
www.foxrockpaving.ie/landscaping-services (code inserted with nothing showin)

All {gallery} tags MUST NOT be inside <strong> or <em> tags.

Offending html tags removed. Still not working.

Could you PM me access to your administration?

Yes. Details have been sent.

The problem is with folders permissions. When trying to upload an image through media manager you will see that you cannot upload. The reason is that joomla tries to write as apache user and not as ftp user. So obviously apache user doesn't have any rights to the folders.

This is a common problem with joomla. Try googling it so as to find the solution or you can mention the problem to your hosting provider.
