Almost certainly water, either in the oil, or because the methanol isn't pure.

How are you removing the water from your oil before processing?  Did you do a hot pan test?

Some jellies can be cracked by adding *more* catalyst and meth, however, certainly not all - so do a test.

If you just add more to the wrong type, it will go from jelly to hard lump.

What was the feedstock?

Photos look like you have liquid on the top and something quite substantial below.

You don't want to be sticking your hand it!!!!

Methanol can be absorbed through the skin ... believe me I know!

Was it all liquid oil with no whites?  You need to get the oil to at least 80 - 85°C and run a venturi and condenser or pump it in a gentle spray (lots of ideas on the wiki) to get it really dry.

As has been said above try reprocessing a small sample.

That looks like what I made with creamy oil from a Chinese restaurant during my first year of biodiesel brewing.  Resembled turds and was totally unpumpable.  The only batch in years of biodiesel making I didn't manage to recover.

By "whites" people mean nasty creamy oil.  The only way is to boil the water out (it stinks!). I heat my oil to over 100C, but you can do it at a lower temperature with a diffuser - see:

Did you get glycerol out before it turned to jelly?

If so...

Take a small amount (1 ltr etc) and add 150ml more methanol, with 3g of caustic added to it (mix the methanol and caustic before additing them to the 1 ltr)

Heat to about 60c, and shake or stir the mixture quite a bit.  Then leave it to stand / cool back to the same temperature as the rest.  Dont keep prodding it, just let it be.

See if the result is a harder jelly, or a 'cure'.

There is no solution without some tests / experiments as not all batches work the same.  You need to test, and find a solution that works - people can tell you the tests, but not what the final conclusion will be : (
