Could you post the link address of the builder page of that character?

is this correct?

Yes.

It seems the homebrew item Wand of the Crystal Skull is the culprit. Stowing the item, and the spell tab works.

What's wrong?

It always worked...

I don't have any custom items to my knowledge, but I'm getting the same problem with my character.  I tried copying it, and got the same problem.  I tried building a brand new character with all the same spell, race, ability, feat, and item selections, and got the same problem.  Multiple browsers on Windows and Safari on iOS show the same problem.  Clicking the spell tab crashes the application.

Error output varies from browser to browser, but here's what Firefox on Windows does:

I narrowed it down to the offending item:  Dragongleam Spear +1

The interesting thing about this item is that it doesn't show up in the equipment search for 'dragongleam'.  To find it, I have to search for 'spear' and scroll.  This suggests there's something structurally flawed with this object.
