I went into the ee promo codes section to look at a promo code and this error came up:
Data Tables Warning: JSON data from server failed to load. Then something about a possible formatting error. How do I sort this asap- this event is now live and heaps of people have been given promo codes. Thanks.

Hi Paul,
That does sounds like a formatting error.
Where exactly is this issue coming up – promotional codes over view, editing a code or in the event itself?
What browser are you using please?

When I log into WP then click on the EE plugin then click on the Promotional Codes link the error comes up straight away. I had entered one promo code last week and just went in to add another when this error came up.

Hi Paul,
I’ve seen this before and it turned out to be browser caching. Can you clear the browser cache and retest please.
Here are instructions on clearing Chrome’s cache:

I would start with theses settings http://d.pr/i/Pc1q

Hi Paul,
Have you added any custom functions to add some CSS recently?
Specifically:
<style type="text/css">
a:hover {
cursor:pointer;
}
</style>
That is being added to the ajax response (plus other files) which is breaking the formatting.
I’m unsure currently how/why that is being called.

Yes I did because I was getting no hover cursor on the ‘Send me an Invoice’ link. It fixed that but looks like its stuffed up something else!

I added that to the invoice_vars.php file.

You’ll need to remove that and add it to a custom CSS file.
I would recommend using a plugin such as My Custom CSS to include any addition CSS you may need.
That should then fix the promo code issue.

OK, thanks Tony for your time, not sure how to add a custom css file but i’ll give it a try with the link you’ve provided, cheers.

The plugin I linked to will do it for you from the Admin.
Once you install & activate that plugin you’ll see something like this http://d.pr/i/D5FG (I’ve already clicked the ‘My Custom CSS’ heading.
Then just add your CSS there, like http://d.pr/i/6dPc
Hit save.
Remember to remove that rule from invoice_vars.php file to fix the promo codes.

Thanks Tony, I can confirm 2 things – removing the code from the invoice_vars.php file fixed the promo code issue, and I added the Custom CSS plugin and added the code there as you suggested which now adds a hover cursor over my invoice link!! Wow what a trip this has been, cheers mate thanks heaps!
