The administrator is getting an error after an upgrade that states Error: "Text/HTML is currently unavailable" when trying to access the HTML Pro module configuration page:
Error: Text/HTML is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException:
Input string was not in a correct format. ---> System.FormatException: Input string was not in
a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer&
number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s,
NumberStyles style, NumberFormatInfo info) at DotNetNuke.Modules.Html.Settings.DisplayWorkflowDetails()
at DotNetNuke.Modules.Html.Settings.LoadSettings() --- End of inner exception stack trace ---
DNN version 9.2.0 and above.
An upgrade from a previous version of DNN was performed incorrectly and the module assembly version is still downgraded, even though the portal has been upgraded to a new version.
If you are only facing a problem with the HTML Pro module, install the most recent version of the HTML Pro module (attached to this page).
If you are also facing other issues related to multiple modules, then we recommend you perform a clean upgrade/installation of the new DNN version (exporting your portals and backing up your database).
The HTML Pro module will be available for installation and display without any issues.
