Hi Rotem,

the error states something about SeoChecker? Have you checked if your version is compatible with the umbraco version?

Just guessing...

Regards David

Hi David. SEO Checker 2.0.1 is indeed compatible with Umbraco 7.11.1

I think this might be the root of all evil, as it appears in my log for almost every action I perform:

 2018-08-08 11:15:35,000 [P9288/D11/T208] ERROR SEOChecker.HttpModules.ValidationqueueModule - SEOChecker: SEOChecker: Error running scheduled task

   at SEOChecker.HttpModules.ValidationqueueModule.TimerCallback(Object sender)

Hi Rotem,

I would post this issue in the SeoChecker forum. Or contact Richard directly. Seems to be related with the package, I think.

Regards David

Thanks, I did. Waiting for an answer from him. Will update this post if I have any new insights.

an update: When removing SEO checker 2.0.1 the error goes away. Thing is, I require SEO chceker, so I don't really understand what does it has to do with saving content.

I literally just ran into this as well.. It's definitely SEO Checker. Have been battling it for a few days now, but today we just realized that SEO Checker has killed all our Croppers. Not sure how best to handle. Rotem, have you found a solution?

I am also seeing a lot of this in our logs

Hi M N. I'm waiting for Richard Soetman to create version 2.0.2 since I cannot seem to install the patch manually. Did u succeed in installing the patch? Richard Van der Meel - Thank you for all the help :)

I Hi Rotem, I have not attempted this yet.

But I will let you know when I have it.

Richard van der Meel - thank you for your kind offer!

Just got the patch from Richard van der Meel - seems to be working, but I'm waiting to confirm if my approach has any foreseeable issues.

Specifically, i changed the extension on the nuget to .zip (since they are just zip files) and then manually grabbed the binaries out of the lib folder and dumped them in my /bin

I removed SEO Checker out of my NuGet for now, just wanted a quick'n dirty test until Richard S has an official fix.

Waiting to hear from Richard van der Meel on whether the exact fix for this issue was purely backend code (binary).

Hope that helps.

Still doesn't work for me. I downgraded for 1.0 for now, cause it seems that it works like that, and i'm waiting for Richrad to release a new version to address this issue. Thanks anyway :)

Sorry for the delay Rotem,

I was mistaken, that other patch did not work sadly.

However, Richard sent me a 2.0.2 that definitely does work. At least from what we can tell. I haven't really stress tested it or regressed any of the main features, but our content manager was able to upload Image Cropper images after I swapped out the binaries.

I am sure he will expound on this in the near future and officially push out the update, but if you want I can send you a link to grab the binaries?

Shoot me an email mnd3unh (gmail)

Hi,

I am running into a similar issue with SEOChecker v2.1.0 and v2.2. On a clean empty or starter kit site, it works fine. Below is the error I am getting. The site I am running have macros, custom editors and data types.
