On some hosts, permissions of 777 are not allowed. If you go to the WPS installation page (in admin), so long as you are on the latest version, the wp-content/wps-content folder should be created if it's not there.

If you havn't got any uploaded user content yet, try deleting the wp-content/wps-content folder and then re-visit the WPS Installation page to see if it creates it (under Image Uploading section). 

Integrity check completed.
The Symposium images/media path could not be created (/var/www/clients/client2/web15/web/beta/wp-content//members), check rights and re-run the Integrity Check

Ah, you are missing something here (the double //).

Under settings, what do you have in the "Images URL" field? For example, I have "/wp-content/wps-content".

Can you use the private mail to send me your website address, admin username and password? I'll take a look.

Thank you for your help
To solve the problem I went into the setting page and you see what I was writing -

I click on "Suggest"

and then I go to my ftp server and I credit wp-content folder wps-content with the 0777 law on the folder and voila that's it play
