I have had a heating control sketch running for several years now but recently I have had to have a new home router. I tried to update the new SSID and PASSWORD in my sketch but when I try to compile it I get the error message:
"Sketch uses 1750313 bytes (133%) of program storage space."
I have changed nothing other than a few characters
under File>Preferences set compile "Show verbose output"
copy the compiler and linker output and paste it using code tags </>
could be a problem with Migration from 2.x to 3.0 - - — Arduino ESP32 latest documentation
Thank you horace
Would you know if I can roll back to v2?

select Tools>Board>Board Manager then enter ESP32 and select the version you require
alternatively change the partition size to Hugh App
This reduced the sketch to 59% from 133% when compiling 
I now have a compiling error saying :
"Multiple libraries were found for "xxxx.h""
That is not an error but a warning. It will tell you which one has been used. If you have a sketch size, compile was clearly successful.
I only got it to compile once.
I had 'rolled back' a lot of my libraries to see if that was causing my original problem. After updating the libraries back to the latest versions I cannot compile. I just get compilation failures
Having more than one version of a library installed can be a serious problem. Best practice is to uninstall the whole library and make sure all files are removed from the sketch/libraries folder, before you install the version you intend to use. The multiple library found warning usually shows up when there is a compilation error, but it is not unusual for more than 1 library to be found, and normally speaking the compiler will pick the correct version.
Thank you Deva_Rishi, I have done that and now everything is compiling as normal. 
Also many thanks to horace for pointing me in the right direction to enable me to compile the sketch to fit on my ESP32 as it always did before
