The most common reason in the past for this behaviour is that your WordPress theme (or possibly a plugin – but that would be unusual) is loading and using the ‘BootStrap’ javaScript library.

But before spending time discussing why and how to fix that, perhaps you can confirm whether this is the case or not. And if BootStrap is NOT being loaded you will need to check for script errors in the web console. If you do not know how to do this I can do it but would need a link to your forum page and, perhaps, an account that enables access to items like the file uploader.

Hi, many thanks for your prompt reply.

Unfortunately I’m not sure whether BootStrap is in use, or how to tell.

I will create an account for you and perhaps that will allow you to undertake some detective work. I will PM it to you.

Thanks again.

I am afraid you have some real nasty stuff going on on the website… Let me start by saying that the BootStrap library is NOT officially supported by WordPress. It has a negative effect on the jQuery UI library which IS the standard supported library and the one that Simple:Press makes extensive use of as do all plugins and themes that abide by the WordPress standards and API.

You have not just one but two components that are loading Bootstrap. This is even worse than the standards issue as it means they are not loading it properly – it they were it would not be loaded twice! One is something called ‘download manager’ and the other is something called ‘featurepro5’ which, I believe, is the WP theme.

These are the main cause of jQuery UI components not working which is showing itself in the start upload button but will effect other things as well.

Just for the record your site is also loading the ‘retina’ image loading script (also from he theme) which is fine is ALL of your images are retina display created but if the files it looks for are not present it just wastes precious time making many, many http requests to the server and has the effect of slowing the page load times enormously. And we are talking many seconds here.

What is causing the forum display to be all over the place and too wide I do not know but I suspect the WP theme as it does appear to be non-standard and something of a mess. But until the Bootstrap issues are sorted out it is hard to tell. The key is getting the bootstrap script file to be loaded before the jQuery UI script bit as your site is loading it twice it is hard to know how that will work.

Thanks for looking into it for me. Looks like I have some work to do!

We are going to change the theme in the next month anyway so hopefully that will address 2 or 3 of those issues. We don’t really like it, it was just what we used to get the site built.

As for Download Manager, that is something we really do need as it manages our download assets. Did a lot of research to land on that plugin so may need to go back to the drawing board.

Thanks again.

Talk to the plugin authors. There is a simple question… is the download manager plugin required on your forum page? If it is not then why is it being loaded up? if it is not loaded up then there is no conflict.

Just coming back to close this out and possibly help others.

Within the WordPress Download Manager plugin there is the option to disable bootstrap, which I did. It has not affected the plugin functionality and the File Uploader plugin now works as expected.

Thanks for your support

How very odd. Makes you wonder what it is being used for. BootSTrap is largely a visual component script.
