Recently, there is a “latex path not specified” WordPress LaTeX bug, it is very weird. Some LaTeX expressions will get rendered and some will not. Will have to postpone my math blogging till it is fixed. Worst case scenario is I have to abandon this blog and move to Blogger (http://mathtuition88.blogspot.com) if the issue remains unfixed.
Testing: 
Hope this bug gets fixed soon. If anyone knows the solution to solve this bug, please inform me in the comments below!
Note: Thanks to Professor Terence Tao who has replied in the comments below and shown us a link where there is ongoing discussion about the highly mysterious “latex path not specified” issue.

There is some inconclusive discussion on this issue at https://en.forums.wordpress.com/topic/latex-path-not-specified-errors-1?replies=33#post-2501402
For me, the strangest thing about the bug is that it is machine dependent – everything is fine when viewed from one machine, but not from another. But it does not appear to be browser dependent!

Thank you Professor Tao for your comment! Everything was fine for me till last night (Singapore time). It is very strange like what you said.

What an inconvenience!

Yeah, it is very inconvenient for us math bloggers… I have to say Blogger is better than WordPress in this aspect (LaTeX).

I hadn’t encountered that, but I haven’t had to do anything complex in WordPress LaTeX in a while.
