Failed Ajax request or invalid JSON returned

Hi,

I've just installed OMP 1.0 beta. Currently, all works great, except for one thing.

When I click in Add publication format, I get the following error:

Hi Vicente,

Depending on how you have your error reporting configured, PHP might be spitting out an error message in the middle of a JSON response. Check your error logs; this kind of thing is also easier to debug if you can dump the contents of the response, but you might need something like Firebug for Firefox to do that. I believe you can also do it with Google Chrome Developer Tools.

Hi Alec,

Thanks for your response. Please, tell me how to get what you need with Google Chrome Developer Tools.

Hi Vicente,

Just trying this out for the first time myself, so bear with me --

• In Chrome, click the wrench icon, then go to Tools > Developer Tools.
• Click on Console, right-click in the blank pane, and turn on "Log XMLHttpRequests".
• Try the action that's causing you trouble.
• Go into the "Network" tab. Find the request that's giving you trouble (should be right at or near the bottom).
• Click the request and you should be able to view its response contents. Hopefully you'll see an error message in there.

Hi Alec,

I thank you for your patience and your clear explanations. You were very specific.

Below you can see the error message. I've solved creating 'temp' folder manually. Have I done well? I don't understand, the 'files' folder had 777 permissions.

Hi Vicente,

Thanks for debugging. That's fine -- I've filed a fix at http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=7923, but if you've manually created the directory that'll solve the problem too.

Note that 777 permissions probably aren't safe to use if you're on a shared server.
