Admin Can’t Upload Images

Hi @dyv156

This could be something related to your server configuration not Wordfence firewall, let me ask you some questions first:

– After trying to upload images, do you get any “blocked by firewall” entries in Live Traffic?
– Any related error messages you can see in the server error log file? (you can ask your web host regarding the location of this file).
– Does this error occur after uploading any type of image? do you upload them via (WordPress Dashboard > Media Library)? or via frontend?
– Try to deactivate Wordfence plugin -temporarily- then re-upload some images as a test.

Let me know how it goes,
Thanks.

TL;DR: check that your server partitions are not full.

I might have experienced a related issue. Started while trying to upload images and failing with “Error HTTP”, like @dyv156. Went to see the log and boy, there were a lot of errors about Wordfence’s database queries, like:

[1533106029  ] Error The table 'wp_wfStatus' is full de la base de datos de WordPress para la consulta insert into wp_wfStatus (ctime, level, type, msg) values ('1533106029.933407', 10, 'info', 'SUM_ENDBAD:Scanning for old themes, plugins and core files') realizada por do_action('wp_ajax_nopriv_wordfence_doScan'), WP_Hook->do_action, WP_Hook->apply_filters, wordfence::ajax_doScan_callback, wfScan::wfScanMain, wfScanEngine->go, wfScanEngine->doScan, wfScanEngine->scan_oldVersions_finish, wfIssues::statusEnd, wordfence::status, wfLog->addStatus, wfDB->queryWrite

But I did the obvious thing first: I took a quick look at the server and of course, the problem was the root partition was full (choking the database, even though WordPress is in a different one). After freeing some space, I can again upload images. I still saw a few errors with the first uploads, but they were probably fixed after the first cron activated, and all seems to be working fine now.

I do wish WordPress would check something as obvious as free space instead of throwing these unhelpful errors:

An unexpected error occurred. Something may be wrong with www.ads-software.com or this server’s configuration. If you continue to have problems, please try the support forums.

Hi @dyv156

Since we haven’t heard from you for a while I’m going to go ahead and resolve this thread. If you have any other questions or concerns, don’t hesitate to open a new one.

Thanks.
