Something has gone wrong in our Dev environment and I cannot figure out the problem.
We have an accordion control that we use and have deployed successfully, and works today in our production environment. I just had a project where I needed to make some updates and have no issues with the control on my local workstation.
I rolled back my changes on the dev server and the control is still broken. This issue came up previously and has simply gone undected in dev until now.
The issue is that no html rendering is taking place. When I remove the AjaxControlToolkit.dll file from the bin folder, I get the expected 'cannot load assembly' message.
The web.config has <add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" /> in it as expected.
Without any error messages shown in the F12 console or to the screen or to any other log I know of, I am out of ideas as to what to do to fix the issue.
What debug tricks might work to solve this one?
