Error msg logging on (ver 4.5.1)

[Dpillay]

Hi

I am currently facing 2 problems

1) When I log on to sugar I get the attached error msg. To clear the error msg and continue working on sugar I need to place the cursor in the url bas and press the enter button. I hope this is not a major problem to resolve. Assistance needed,pls

2) My other problem is that I need to upgrade to the latest version of sugarcrm community edition with out losing my data. I follow the steps but seem to get stuck (system hangs) on #1 system check in progress



Thanks in advance for your help
