Invalid postback or callback argument. Started By Marnix Hi, We're running a lot of DNN installations with a lot of different versions (from 8.04 to 9.9.1) When I filter the eventlog on page load exceptions, I can see almost every dnn installation has errors like these on the login page.

RichTextEditor disappears after PostBack Started By mouserdeveloper I believe I am experiencing a bug where the Rich Text Editor disappears after the page performs a postback. I created a fresh install of DNN 09.09.01 and on the default home page, I went to Edit Content for one of the HTML modules. The Rich Text Editor(RTB) shows up with the content in it. I then go down to the combobox underneth it and select Basic Text Box. The basic text box shows up with the content written out in HTML in it.

Local Install and Run Started By DaveHassall Hi I'm such a fan of DNN that I'm starting to use it to build management systems for myself and my clients that run on a local PC. I'm experiencing something I find quite bizarre, it loads and run noticeably slower that external websites. Incidentally I experience the same for my hosted websites if I run them on my hosting platform. It takes longer to run 'inside' a PC that it does to run it across the Internet. (Related) I also have built a DNN Intranet at work and again it's slower to...	1	1508	1	5/22/2021 10:06 AM by DaveHassall

Storing DNN Cache in Redis instead of default DNN file Started By justinv Hey all! I'm relatively new to DNN, and there are some performance issues with dynamically loaded information from .xlsx files. We think it will be beneficial to have DNN cache these items to Redis instead of the local file, and I've searched pretty extensively, but haven't found how to fit the pieces together. Any help or even a point to where I can read further into the DNN/Redis connection underbelly would be greatly appreciated. Thank you!	1	1732	1	5/8/2021 2:28 PM by justinv

Installation Performance Started By srinath972 We have upgraded DNN version from 5.6.8 to 6.2.8 We have 20 modules which are installed during portal creation. A module used to take around 5 seconds to install in version 5.6.8, But the same modules now take around 40 seconds which is a lot. We started the upgrade from 4.8.3 initially and did not face any performance issues till this version. Could it be old '.dnn' manifests, old xml formats, release notes and license files missing from modules etc. please share any i...	3	1754	2	4/16/2021 5:30 PM by srinath972
