Is there a trick to starting the upload?
I can select a file, but nothing happens when I click on “Start upload”. When I hover over “Add files” the button changes a little bit, but nothing happens over “Start upload.”
has this behaviour just started? I don’t see that you have recently downloaded the uploader plugin so has it been OK in the past?
The issue is almost certainly that you have activated something that uses the BootStrap JS library which is unsupported by WordPress and causes issues with the jQuery UI library which IS supported.
So if this is new behaviour you need to look at what you have added to the site recently. If not new, then the culprit needs to be found.
Also -are you completely up to date with all of your plugins- WP AND SP ?
This is a new install, but I had the old plugin that I updated. Everything was up to date, but I deactivated some plugins and then it worked. Thanks!
OK. Good. If the use if Bootstrap is the cause (and that is the most common manifestation) then it is possible to work around it but it would need a small code change to the offending plugin.
Just figured it out, it’s Perfect Easy & Powerful Contact Form Version 2.3.0 | By Piotr Moćko

I bought it a while ago, but haven’t even used it yet.
Have just installed the version from the WP plugin repository (i.e., NOT the ‘pro’ version) and it doesn’t actually give me any problems. Seems to leave the forum page alone – which is what a good plugin should do.
I think i asked before but are you up to date with SP upgrades? I.e., currently using 5.7.1?
I have a client with this exact same problem. I wonder if it has creeped in with an update somewhere as he mentioned to me it’s started doing it some weeks ago. I do his regular updates so am confident he wouldn’t have added anything as far as plugins go so can only assume an update somewhere broke things.
Could it also be outdated PHP/MySQL and other server side software? Unfortunately he doesn’t host with me and his host has been slow to update and prefers to keep with earlier stable versions.
Load their forum page and view the source in the browser . Do a search for ‘bootstrap’… Very doubtful it is old server software, If it was too old then WordPress would not run.
Everything is up to date! I just checked it again, it is the premium version of that contact plugin, upload won’t work when it’s activated.
Would you like me to email it to you or contact those guys?
You could ask them how it can be turned off for a specific page… If it is not needed on the forum page – for example – then why load it up in the first place.
You could also point out to them that bootstrap is unsupported by WP and, worse than that, has a negative impact on the jQuery UI which IS supported. The trick to get things working is to ensure that the jQuery UI is loaded AFTER bootstrap so perhaps they could give that some thought and properly accommodate plugins that do stay with the standards.
