I'm currently running Umbraco 6.1.6 and while trying to install Contour 3.0.18 yesterday via the Umbraco Package Repository, via local file upload and via manual install I kept receiving an error upon installation stating "web.config could not be updated." Permissions have been set to read and write for the web.config and after the installation, Contour had in fact updated the web.config. After several installation attempts, we still received the error last night once more but this time we were able to create forms. When saving though at times, the field would not save properly and we would receive the "Field could not be saved" popup at the bottom of the screen. To fix this we extended the maxJsonLength to 1000000000 in the web.config and this seemed to work for a short period of time until we started receiving the error again. Just now after saving a form and inserting it into a rich text editor, instead of displaying the form properly it displayed an error that said "Object reference not set to an instance of an object." After publishing, the form has deleted all of the steps and fields I created and another form has deleted two of its steps randomly. On a side note, for some reason the date picker field type won't render properly on the front end and only displays as a textbox (when clicked no datepicker pops up). Thanks in advance. Below is my web.config with my smtp settings and connection string removed for security purposes:
