Thank you very much Rattus, its now working fine. Can you please let me know the changes you did to make it work, just in case I encounter the same issue on another website or someone else has the same issue.
I have cleared the cache from my browser but the issue still persists, please see attached screenshot. I have also tested on another computer that never opened that website and its same. Chrome and IE displays correctly. The strange thing is whilst in Firefox, if I make the browser view smaller and then maximize it again, the galleries then displays correctly in columns across the content width.
Thank you again for you time on this.
Hi Rattus
Thank you for your quick responses but unfortunately I have tried changing the settings as you indicated but still behaving the same. I have even put 1000 and that didn’t help. Can I send you the login details so you can check further?
