I'm using texmaker, and to show the pdf file (internal), I used -synctex=1 to show it in the position where i'm writing the code.
I worked pretty well for me before, but it has stopped working for 2 days. What can I do?
Try to remove blank spaces in the path to the tex file.
Edit: check for non-regular characters in the file path and replace them with standard ones.
For example, to make the synchronization source-pdf with Synctex functionality in TeXMaker work for me i needed to remove a ü in the file-path, which is a german vowel.
