Update page after adding media library image, get 404

  • I’ve been having problems with an inherited website. The latest problem is that when we insert an image stored in the media library to a page, we get a 404 error upon updating the page and the changes are not saved. In a few cases, we get the 404 error as we are inserting the image (and the image is not inserted).

    Tonight, I updated everything – WP 3.4.2 > 3.5.1, updated all plugins (and, yes, tried doing all of my editing with the plugins disabled). I had the problem before the updates, and I have the problem after the updates.

    On one page, I was able to successfully insert the image “from url” (despite that url pointing to our own media library). While I am able to insert images using the url (and see them just fine in the visual editor) on other pages, when I click Update to save the page, I get a 404 error.

    I am able to save the page if I haven’t made any changes AND if I make changes to the text. But I can’t save with an image in there.

    Here’s the line of code I’m attempting to add:

    <img src="https://thrivingplanet.org/elisa/wp-content/uploads/2013/03/Screen-Shot-300x91.jpg" alt="Screen-Shot" width="300" height="91" class="alignnone size-medium wp-image-1590" />

    I tried stripping out everything – class, width, height – and leaving only the <img src="..."> code. No dice. I still get a 404 error upon saving the page.

    Here’s the page where I am trying to insert the code above:

    https://thrivingplanet.org/england-gaunts-house-dorset-may-24-26/

    Anyone have any thoughts? I found a few threads about 404 on update, but all of the posts I read were 3 or 4 years old and it looked as if their content was saved, whereas my changes are not.

    TIA, ~KJ

    It is definitely less than 5.4 … I believe 5.2.17. Not much room to adjust that, as far as I can tell.

    This problem WAS resolved, although not by me (I had to leave on a business trip). I am waiting to hear back from the fellow who fixed it – he said he found malicious code and I want to know what tool he used to find it. I used Anti-Malware and found nothing positively malicious.

    Will update here when I have a more complete answer. Until that time, I will leave the topic marked as unresolved.

    Do you have more details regarding the solution?
    I am having the same problem and my site was indeed hacked a few days ago. We have restored it since then but trying to edit pages now I get 404 after inserting media in the page so your hint regarding malicious code is highly relevant in my case

    Would you please provide more details?

    yanay please start your own topic. Your problem is not similar to this one.

    Perhaps I misunderstand, but it sounds like it does relate? Trouble is – I did not resolve this particular problem and I am not in contact with the person who did. I will follow up with our intermediary.

    In the meantime, I have installed WordFence on several sites and like it. During the “crisis” above, I could not install it successfully, but if you can install it, I would recommend it.

    Hi
    My problem was very similar:

    when we insert an image stored in the media library to a page, we get a 404 error upon updating the page and the changes are not saved

    The solution in my case was to tweak mod_security which was recently installed on the server. I did not handle that so I too am not sure what was the fix exactly. But in my case at least it was not malicious code

    Thanks

    Hello,

    Has anybody found a solution for this? I ran WordFence on the site and it did find some malicious files. I have cleared the site of malicious files and ran the scan a couple more times and both times it came out good. I’ve removed the images I had uploaded before I cleared the malware and uploaded them after the scans. I still get the https://www.site.com//wp-admin/post.php URL with a blank page (on Safari) whenever I click the Update button. I appreciate the fact that a couple of you had it resolved by someone else, but if you could insist on finding out how they did it, I would really appreciate it.

    Thanks.

    @elomeli – you need to start your own thread – this one is way outdated.

    You can do so here:

    It’s only two months outdated, I think it’s a reasonable timespan. I’ll start a new thread either way, but I think the history in this post will help. Any clues would be appreciated. Thanks.
