It’s hard to say exactly what the problem is but clearly you have some JavaScript installed – either from your WP theme or from another plugin – that is forcing the jQuery script to stop processing so anything after the conflct just doesn’t work.

It might be something as is discussed here – https://simple-press.com/documentation/codex/faq/troubleshooting/what-is-this-jquery-conflict/ – but is just as likely to be a bad script that doesn’t properly use the WordPress standards. Look at this article and see if the condition on there exists. Otherwise you may have to just briefly try with a standard (default)  WP theme or by deactivating plugins one at a time to try and find the source of the conflict. Hopefully be something simple.

The ‘void’ status by the way is as it should be.

I’m shutting down plugins left right and centre but getting the same error message.

Is it possible to reinstall  SP without losing all my posts and structure?  

You can copy the plugin code files back in from a fresh copy. You wont be able to ‘re-install’ as such without losing all of your current data.
But the chances that you have a corruption in an SP file is extremely remote and slim and of there were it is unlikely to cause the symptoms you have described.
You can give me a link to your forum page so I can look at it for you – doesn’t mean I can find the culprit but worth looking at…

 It definitely seems to be a jQuery issue.  I shut down all the plugins (apart from SP, itself, obviously) and it had the same result.

The error message in the “Inspect Element’ window says:

Uncaught TypeError: Cannot read property ‘split’ of undefined                    sp-plugin-scripts-footer.js?ver=511:4
Uncaught TypeError: undefined is not a function (index):2482 

I attach the problem file as a pdf – maybe you can see something there that can be fixed.

Attachment? And if there WERE an attachment what file are you actually talking about?

I see from the paste that you seem to be caching the javascript into a single file. Generally a good idea but perhaps not so helpful when needing to troubleshoot. I would suggest you turn that off until the problem is sorted (forum admin > options > combine and cache scripts…

And I will ask again for a link to your forum page? It is often much easier to take a look.

Well, I thought there was an attachment when it left here because I had to convert a js file into a pdf due to the restrictions on the kind of files we can send. Anyway, I’ve loaded it again.

The url is www.flat-chat.com.au/forum.  Our messages crossed over so I didn’t get your original request for it.

I have been using the “Inspect Element” option in Chrome.

I have switched off the js and css  cacheing (didn’t even know they were on) but I’m going to reactivate some of the plugins so you can see how it works (or doesn’t).

Well I never!  Switching off the cache’s seems to have fixed it.  Is there any harm in just leaving them off or is there an underlying issue that needs to be addressed?

Spoke too soon.  

I can now see the new posts’ headers  when I click on that button but I can’t open,  edit or approve them.  And the admin pop-up menu isn’t working

First thing…

Can you go to the forum admin > Options > General Settings

Make sure ‘Use auto update’ is turned OFF and also make sure you Update the form with the button at the bottom. Does that make any difference?

And if it does not would you be able to add a constant to your wp-config.php file as a temporary measure?

define('SP_SCRIPTS_DEBUG', true);

which might help with the analysis.

And no – leave the script cache turned off until this is resolved…

Oh – also try deactivating the SP Admin Bar plugin temporarily…

Turning auto update off means I can now see and use the pop-up Tools menu.

However, I still can’t use the “View” button in the new posts menu and users still can’t login, post or reply.

I have added the code to the wp-config.php file as suggested.

Just got the message about the admin bar and I have deactivated it.  

I can now log in at the front end (so I assume ordinary users can too), and reply and post.

Everything seems to be normal – except for not having the admin bar, of course.

I will keep checking during the day for a permanent solution.

Thanks

Well – can you now first turn the auto-update back on and again – make sure you update the form. If all stays good then turn back on the admin bar and let’s see what happens…

It all seems to be working fine again.  Wish I knew exactly what had gone wrong but happy to take the result and plough on.  Thanks for all your help.
