I'm developing locally and using Mamp Pro. Basically MySQL is having trouble starting and here's the error message from the error log:
Any idea how to resolve this?

2017-03-02 00:39:08 7fff7b652000 InnoDB: Operating system error number 2 in a file operation.
InnoDB: The error means the system cannot find the path specified.
InnoDB: If you are installing InnoDB, remember that you must create
InnoDB: directories yourself, InnoDB does not create them.
InnoDB: Error: could not open single-table tablespace file ./freshwp/freshwp_wfblocksadv.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.

From the above code the error seems to be:
2017-03-02 00:39:08 9518 [ERROR] InnoDB: Attempted to open a previously opened tablespace.

Recently encountered similar issue developing locally w/ MAMP. Log included "Database was not shutdown normally", similar error messages after that point, and the suggestions as well. Below are steps that resolved it:
Hadn't yet done much work with the DB, so was willing to lose data or even reinstall MAMP; if your situation is different, probably best to first backup your db directory to a .zip file so you can try something else later if no luck.
Hope this helps.

UPDATE:
Have found it faster to replace steps 3 and 6 with the following:
3. Create a temporary folder somewhere handy; select all the .idb files and move them into that folder.
6. Move the files back into the original folder from Step 2.
