Anyone else not getting a response from blogdown serve_site()?

Running serve_site() either from Add-ins or in console, I get the red button indicating something is happening for about 30 seconds and then it goes out and i get a new line >
A feww messages of process show up but the output is not rendered in the Viewer

Any suggestions

Hello pssguy ~ I have had similar issues. Did you manage to find a solution?

Hello again;
I just solved the problem on my system. I had just updated my R version to

R version 3.5.0 (2018-04-23)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows >= 8 x64 (build 9200)

I thought to check the package "servr" a while ago and got an error message when I sought to load it

Error: package or namespace load failed for ‘servr’:
package ‘servr’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version.

So I re-installed "servr" and the Viewer now works for me when I run blogdown::serve_site().

Hope this helps
