The "New album" button is no longer clickable. I have not added any plugins or made any changes. It just happened.
It can't have JUST happened (unless changes were JUST made to your theme). The problem is in how your theme is coded.
Your theme is loading javascript resources in a sequence that will not work. It may be okay that you are using a jQuery version that is later than what CPG1.5 was designed for, but it needs to be loaded BEFORE most of the other CPG javascripts.
Also: you should keep some other standard theme (e.g. curve) in your themes folder so that functionality between themes can be checked.
Then http://<YOUR_CPG_SITE>/index.php?theme=curve should display your gallery with the curve theme.
Unless someone has made a change to my theme (highly unlikely as I am the only one with access to the site).
I can't update the gallery anymore.
Would appreciate help.
Can I pay someone to fix it on this forum?
Did you get/purchase the theme from somewhere? The theme author should correct the issues.
If that's not an option ...
You got an email from me. Zip your theme folder, send it to me, I'll make appropriate corrections and send it back to you.
It looks like you fixed it. Please mark the topic as solved.
