I am getting this error message using Google Chrome ONLY. It was working fine before and all of a sudden this keeps happening when I am uploading photos.

I cleared the browser history and cache and hard reloaded the page and the message still shows.

E_USER_NOTICE: Security Error: Invalid _CSRFToken. Try reloading or going back to previous page.

Any help or suggestions please?

Hi wevolutions, 

Sometimes I come across this error when there's an http/https mismatch, which is something that may differ between browsers. Can you try on chrome using the HTTPS url and let me know if that fixes the issue?

Thanks,

Both http and https give the same error. It does not happen with other browsers so I am guessing there may be some issue with my Google Chrome.

Hi wevolutions,

That is very curious that it would only happen in Chrome. Do you have another computer you could use to see if it's machine-specific? Or you can send us a 2nd-level support request (https://www.interactivetools.com/support/request/) with the instructions to reproduce the issue and we can try out a few browsers on our end. If it's happening in Chome in general, it'd be worth finding the source of the issue.

Thanks,

It happens ONLY in Chrome and it is machine specific. Other computers and browsers work just fine. I cleared the cache many times, I deleted cookies, Google Chrome has the latest version running, I am not sure what to do again. I should figure it out soon enough.

UPDATE: The issue is with using the Flash Uploader on Google Chrome.

I usually have about 10 photos to upload at one time so I use the flash uploader which makes it very easy to do this.

Since a few days ago, this issue started happening with the Security Error.

Is there an updated version to allow multiple file uploads at one time without using the flash uploader?

Yes, the flash uploader was replaced a number of years ago.

This error message has happened to me for years with CMSB and Chrome. Anytime I am in the middle of updating a record and don't save it within about 30 minutes, I get the error. I can open the record in a new tab, enter the data again and click save without error. I always thought of it as a sort of timeout error.
