*SOLVED*: esptool often fails to find sub-included files

For some reason (my lib directory may be messed up) the esptool in Arduino IDE keeps on complaining that it can't find this or that .h file that an included file references. Eg: C:\Users\matt\Documents\Arduino\libraries\WebServer\src\WebServer.cpp:27:17: fatal error: md5.h: No such file or directory

I've been having to download each one from github, but it's getting tiring. Is there any guess as to what is wrong?

Please post a link (using the chain links icon on the forum toolbar to make it clickable) to where you downloaded the WebServer library from. Or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries in the Arduino IDE or Libraries > Library Manager in the Arduino Web Editor) then say so and state the full name of the library.


*** SOLVED: I found that removing the Core Libs and re-installing them solved the problem. ***
