Title: Error 404 Last modified: May 24, 2024 --- # Error 404 * [spiwee](https://wordpress.org/support/users/spiwee/) * (@spiwee) * [2 years ago](https://wordpress.org/support/topic/error-404-104/) * I get a 404 error when trying to access Media Sync. I see the page wp-admin/options- general.php?page=media-sync-options appear for a moment then I get a redirect to a URL that looks like this: z0f76a1d14fd21a8fb5fd0d03e0fdc3d3cedae52f?wsidchk =28950093 I have this problem on several sites. I looked a little in the forums, it seems that it could be a Firewall problem. I disabled Wordfence on a site but that didn’t solve the problem Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [erolsk8](https://wordpress.org/support/users/erolsk8/) * (@erolsk8) * [2 years ago](https://wordpress.org/support/topic/error-404-104/#post-17778617) * Hi [@spiwee](https://wordpress.org/support/users/spiwee/), it sounds similar to this issue: [https://wordpress.org/support/topic/media-sync-page-404/](https://wordpress.org/support/topic/media-sync-page-404/) * But that issue just resolved itself so I still don‘t know what was causing it. Googling “wsidchk 404” makes me guess it is some Cloudflare issue (cache or firewall): - [https://community.cloudflare.com/t/cloudflare-caching-issue/341549](https://community.cloudflare.com/t/cloudflare-caching-issue/341549) - [https://community.cloudflare.com/t/disabled-webshield-from-inmunify-and-still-sometimes-i-get-404-errors/594711/3](https://community.cloudflare.com/t/disabled-webshield-from-inmunify-and-still-sometimes-i-get-404-errors/594711/3) - [https://wordpress.org/support/topic/redirecting-to-404-page/](https://wordpress.org/support/topic/redirecting-to-404-page/) * And you probably shouldn’t disable anything in the long run. It’s best if I could replicate it and handle it somehow in the plugin. But it would help to know what is causing it exactly. Is it some special hosting, some plugin and how to configure all of it to replicate the issue. * So any help with this is greatly appreciated. * Erol * Thread Starter [spiwee](https://wordpress.org/support/users/spiwee/) * (@spiwee) * [2 years ago](https://wordpress.org/support/topic/error-404-104/#post-17778733) * Hi [@erolsk8](https://wordpress.org/support/users/erolsk8/), * Thank you for your prompt response. In fact I had seen the links you indicated. This is very strange because the plugin works very well in my development environment, which works with Cloudflare!It is on sites hosted by the French supplier OVH that it does not work. OVH has a firewall but I don’t want to disable it. No idea of their architecture… * Plugin Author [erolsk8](https://wordpress.org/support/users/erolsk8/) * (@erolsk8) * [2 years ago](https://wordpress.org/support/topic/error-404-104/#post-17778832) * Thank you for the details. Well, maybe you can get in touch with them and tell them to whitelist requests to this URL: [https://mediasyncplugin.com/](https://mediasyncplugin.com/) * If that’s even the issue, I’m not sure what else it could be. * But eventually, I’d like to solve it within the plugin. * [saibotknif](https://wordpress.org/support/users/saibotknif/) * (@saibotknif) * [1 year, 12 months ago](https://wordpress.org/support/topic/error-404-104/#post-17825078) * I have the same problem. Getting this in the URL: z0f76a1d14fd21a8fb5fd0d03e0fdc3d3cedae52f? wsidchk=1319860 * I am using big Swedish hosting provider, not Cloudflare. - This reply was modified 1 year, 12 months ago by [saibotknif](https://wordpress.org/support/users/saibotknif/). * Plugin Author [erolsk8](https://wordpress.org/support/users/erolsk8/) * (@erolsk8) * [1 year, 12 months ago](https://wordpress.org/support/topic/error-404-104/#post-17825094) * Sorry to hear that [@saibotknif](https://wordpress.org/support/users/saibotknif/) but the question is – how can I replicate this? * If someone can share these problematic hosting providers (their firewalls probably) and how everything is configured, I’d be happy to give it a try in fixing it. * [saibotknif](https://wordpress.org/support/users/saibotknif/) * (@saibotknif) * [1 year, 12 months ago](https://wordpress.org/support/topic/error-404-104/#post-17825118) * This hosting provider is Loopia (loopia.se) in Sweden and I do not have access to their firewalls. * Its stange that the page wp-admin/options-general.php?page=media-sync-options is shown for less than a second then I get redirected to a page with error 404 [https://domain.se/z0f76a1d14fd21a8fb5fd0d03e0fdc3d3cedae52f?wsidchk=17405656](https://domain.se/z0f76a1d14fd21a8fb5fd0d03e0fdc3d3cedae52f?wsidchk=17405656) * Plugin Author [erolsk8](https://wordpress.org/support/users/erolsk8/) * (@erolsk8) * [1 year, 12 months ago](https://wordpress.org/support/topic/error-404-104/#post-17828304) * There is now a new version 1.4.3 which should resolve this 404 issue. * Please let me know if that helped. * Thanks - This reply was modified 1 year, 12 months ago by [erolsk8](https://wordpress.org/support/users/erolsk8/).
