Dear,

An exisisting MW 1.8 has been upgraded to 1.31

Database has resortored and extensions have been upgraded.

Although I can import Templates (exported with all versions) and modules, I get the following errors....

I have no clue anymore... anyone ?

Lua error in Module:TNT at line 157: attempt to index field 'data' (a nil value). Lua error in Module:TNT at line 157: attempt to index field 'data' (a nil value).

Lua error in Module:TNT at line 157: attempt to index field 'data' (a nil value).

It looks like you need to install Extension:TemplateData. Module:TNT (or at least the module of that name that I checked on the English Wikipedia) uses this extension at line 157. It also tries to load TemplateData datasets from Wikimedia Commons, so you will probably also need to make "c:" a valid interwiki prefix for Wikimedia Commons from your wiki, if it isn't already.

The lack of TemplateData would just garbage output, I don’t think it would throw an error. What gives this error is the lack of Extension:JsonConfig (or lack of proper setup). A recent edit to the module gives a more useful error message in this specific case.
