[support] IMCE not showing

I was having some problems with IMCE and FCKEDITOR so I upgraded both and now when I try to upload a image, the IMCE pop-windows don't show the "browse server" button. I tried removing all the tables of fckeditor, all {variables} with imce and fck, and the modules reference in {system}; but after reinstalling I see imce configuration is preserved. Where is the IMCE configuration saved? -- *La vida és com una moneda, la pots gastar en el que vulguis però només una vegada. *La felicitat ha de ser compatible, compartible i cooperativa. *Envellim quan els records superen les il·lusions. *Als llocs desconeguts només s'hi arriba per camins desconeguts. *Abans d'imprimir aquest missatge, pensa en el medi ambient.
