I have installed the plugin vim startify which worked fine in my remote server where I use it. Something happened (I think an upgrade) and the plugin no longer seems to work! But I don't get any error e.g. when vim starts. How do you track down the problem in such cases?
First, check that the plugin is correctly installed; its scripts must appear in
Then, check what artifacts it defines (commands, mappings, autocmds), and verify they're there via
:verbose map ... and
:verbose command ...,
:verbose autocmd ...
Finally, trigger the plugin functionality while capturing a log with
vim -V20vimlog. In the log (or alternatively with
:debugging), you can observe what the plugin is doing, and hopefully locate when and where it goes wrong.
