Join block not working anymore

Hi everybody.

The join form on my join.php is not appearing anymore.

Instead I have : Profile Fields cache not loaded. Cannot continue

I look here  around in the forum but could not find a solution.

I have dolphin 7.07 since month and it was always working.

No change was made in the join form or profiles felds.

I clear all the caches and deactivate all the cache, without success.

I also moove block around in the block builders, but here also without success.

I will be very thanksfull for anyhelp.

Ok, looking longer in the forum I found something that help me.

All the fileds was just gone from the join form (who know why).

So I just had to replace them in admin/Profile Fields/join form

If this ever happen to somebody else

Ok here I really need some help :-(  Please.

After I put all the flieds back thrue the admin panel on the join form, everything was working for fews days.

And today, it was all gone again !!!!

Any suggestions will be welcome.

Thanks
