Morning Jarmila,

Try changing the permissions to 755 and see if that works.  Different servers can have different requirements

Hello Paul,

I tried, it didn't give 500 Error, BUT upon testing it gave "There was a problem during the comment insertion"  message. Any other ideas, please? 

Hello again Jarmila,

Some more thoughts...  in no particular order...

• Try clearing your browser cache and cookies before testing, after making any changes 
• The Guestbook Object has to be saved with a .PHP extension (see Page Properties, Expert window)
• In the Guestbook Object properties window, check very carefully the path to the 'Subfolder on the Server where to save Data' (under Data Save Settings)
• The subfolder referred to above must physically exist on your server (NB: X5 will NOT create it for you) and the folder must have public write access permissions
• Go to this URL...  http://www.celebrityfragrancesshop.co.uk/admin/login.php  and enter your Username and Password as defined in Access Management (Step 4 - Advanced Settings)

PS: You could also try adding a slash to your Website Address in Step 1 - General Settings if there isn't one there already.

i.e. http://www.celebrityfragrancesshop.co.uk becomes http://www.celebrityfragrancesshop.co.uk/

Some have reported success using this method
