Color not changed and losing style

Dear Axel, Thanks for your answer. I changed the host to another host provider that allows me to have 256M. I moved all the files to the new location and the database also. Everything seams to be work however when I tried to change the background color with the color costumizer the color is not changed. Also when I activate the Aggregate and compress CSS files. and Aggregate JavaScript files. the site loses all the style. Could you help me how to investigate the error? Best regards, Eduardo Catarino PS: I would like to conrtibute for the Opigno portuguese translation. What should I do?
