Upload failed message on text posts

Just posting some further information in case anyone is able to help:

In summary, my issue is that third party apps don’t seem to be able to post to my self-hosted WordPress site. The WordPress app generates an “Post Failed to Upload” error, even when it’s a simple text post. The WordPress app is connected to my site as I can view all my media within it, upload media and see installed plugins and their status. I can upload images too from the app and they save to my media library as you’d expect. It only appears to be uploading / publishing a post that isn’t working.

I’ve inserted two screenshots below – one showing the banner saying post failed to upload, the other one showing a list of posts with the top one saying upload failed. Any help would be much appreciated.

• My URL: https://www.simonssite.com
• WordPress mobile app version: 23.81
• App platform: iPad OS
• Platform version: iPad OS 17.3
• Device model: iPad Pro
• Troubleshooting steps I’ve tried: validating xml-rpc (seems to be ok), disabling all plugins (no difference)

However even just trying to upload a plain text post I get the message “upload failed”.

Without uploading the error log, can you repeat the upload then look in your site’s error_log file for the corresponding error? If there is one?

Also when I visit your site, I am getting SSL_ERROR_NO_CYPHER_OVERLAP errors and cannot view your site.

Hi Jan, thanks so much for the response and for letting me know about the site being offline. That only seems to be the case with www. in front of the domain so I’ll get that checked out.

I’ve actually hired someone to check the other problem out for me so will report back if it gets fixed or once I get a chance to check out the logs. Thanks again!

I tried to visit the?https://xmlrpcvalidator.blog?address listed in FAQ but it just says “Coming Soon”.

My apologies for any confusion. The troubleshooter site was moved so the correct URL is now https://xmlrpc.blog/.

That only seems to be the case with www. in front of the domain so I’ll get that checked out.

This needs to be resolved, otherwise uploading to the site address https://www.simonssite.com will not work.

In the meantime, try logging out of the app, and this time when you log in again, enter the address simonssite.com without the www subdomain and see if that helps.

Thanks for all your help – so the www version of my site is apparently down to a SSL certificate mismatch which I’m checking with my host. However I did want to come back on the other error I was experiencing when trying to publish a post.

I tried to save posts using the browser install of WordPress and that didn’t work either, with me getting a “failed to insert post” error. In the end I worked out through sheer trial and error that the problem only seemed to occur if I had typed an emoji character in the post. Removing any emojis allowed me to save drafts and publish as normal. Uploading posts from Ulysses the third party app also worked if I removed any emoji.

I have used emojis in my posts before so not sure why this is now an issue but it seemed to have fixed the problem for me! Thank you again for your help.
