There are 6 blocks, 3 on each side and 2 long blocks for each end, I can insert credit in each easily except one middle, means anything?
Why is this happening to an oak table?

ok try a different tack
insert the extension leaf and apart from the point it goes through the table base mark on any cross timbers it touches with chalk
then follow those timbers and note any gaps between any timbers en route to the side rails and try and see iff you have any loosness or movement by perhaps grabbing the cross rail centrally and wiggle it quite heavily

Tried nothing wiggling, very solid.
The 2 side rails assembly have failed, don't know why both same time. I took all screws of the 6 side blocks and 2 end blocks and still no movement of any part, even the blocks are fixed on somehow?
Only one thing if it's that, whether jointing biscuits between side rails and front rails have failed?

will usually be dowels or a large glue area caused by the mating surfaces having grooves and mouldings increasing the contact area and because they are male and femail they interlock but in this instance is will be no more than a short stub tennon [to stop it showing at the face]to match the groove for the boards to fit into
not that easy i am afraid glue seals the surface and into the grain hence its strength
the problem you now have is even iff you get a good clean surface you have the grain sealed
now you will get some bonding, it will be fully surface on old glue so perhaps only 50-80% as good so you need to stop the load putting so much weight in the wrong place to give it a chance to last
any one who has cleaned out and re glued a loose chair will tell you it wont last long
somthing like 10mm 4 inch stainless steel rods may help??

metal dowels?
yes indeed there must be a heck off a lot off strain to break a glue bond so now you can not replicate the original strength you need to go ott rather than a bit stronger with wood dowels that will probably fail where as 10mm or even 8mm [at little saving ] will do the job as near to as strong as you can get without added external support
and shop around you may get stainless at a far cheaper price that was a fully random link
It looks to me that the slats in the centre of the table have absorbed some moisture from the atmosphere and expanded across their width. This expansion has pushed the side rails away from the table. As the centre slats are thinner than the side rails this expansion has pushed mainly against the top of the side rails causing them to sag downwards.
Suggestions?
