Solution for WP 4.7.1 bug causing “You must upload a .wie file generated by…”

PS. Thank you to everybody who checked this support forum before leaving a one star review for an issue not caused by the plugin. That’s the way to go on www.ads-software.com and I appreciate it.

Version 1.4.1 of this plugin applies a temporary workaround only for WordPress 4.7.1. It will cease automatically when WordPress 4.7.2 is released, since that will have the permanent fix. You can simply update this plugin now to avoid the issue. It’s no longer necessary to install the other plugin mentioned above.

I am on 4.7.2 and still having this issue. When I click on the .wie file to upload I get the message saying “You must upload a .wie file generated by this plugin // I have tried it with and without the “Disable Real MIME Check” plugin installed. Neither works.

@pennypackmo Thank you for reporting this. It looks like WordPress 4.7.2 was rushed out to deal with a security issue before this particular bug was fixed, so the problem remains.

Does it work on 4.7.2 if you activate this plugin? https://www.ads-software.com/plugins/disable-real-mime-check/

I will need to update WIE to consider 4.7.2 as having the bug, too. It was expected that 4.7.2 would fix the bug but it doesn’t look like there was time to do that. Stay tuned, I need to make some time to deal with this…

Thank you for replying so quickly. Unfortunately I already tried installing and activating the Disable Real MIME Check plugin and it was still not uploading the file ??

If you deactivate all plugins except WIE and the MIME plugin, double-checking that it’s not just installed but also active, does it work?

I’m going to try and test this myself tomorrow.

I’m seeing the same issue and the MIME plugin isn’t helping for some reason. But, I am able to apply the workaround in WIE to 4.7.2 in addition to 4.7.1 (it currently only targets 4.7.1). I’m working on updating WIE…

The permanent fix for the uploads issue is scheduled for 4.7.3 but I’ll get the WIE update out before then. Today or tomorrow.

@pennypackmo I just released version 1.4.3 of the plugin to deal with this on WordPress 4.7.2. Does updating cause uploads to work for you?

@stevengliebe – WOW! You are amazing. Yes! It is working perfectly. Thank you so very much!

Confirmed, the new update fixes the issue. Big thanks to @stevengliebe for the speedy fix.

@pennypackmo @themovation Thank you both for confirming the fix.

@stevengliebe

I’m seeing the same issue and the MIME plugin isn’t helping for some reason.

That’s because Widget Importer & Exporter runs later than Disable Real MIME Check and overrides its filter (so far so good), but in doing so, it returns null instead of the original $data array passed to the function. This leads to undocumented behaviour (wp_check_filetype_and_ext() should always return an array, not null) and essentially breaks the plugin for WordPress versions other than 4.7.1 (and now 4.7.2).

To correct the issue, please change return; to return $data; in includes/mime-types, line 54.

@sergeybiryukov Thank you very much for catching that and taking the time to tell me. I appreciate it. Also for the entire workaround itself. ??

I just released 1.4.4. It returns $data instead of null to resolve this. Thanks again, Sergey.

Cannot make head nor tails of this thread. What do I need to do as of February 4th to generate a .wie file. I’m on the latest version of WordPress as of the time of writing (4.7.2) and it just is not working for me.
