issue when trying to upgrade

Im trying to upgrade 7.5 to 7.7 using the upgrade wizard. I have followed all the prerequisites. The upgrade file does not upload to the server, and just shows uploading indefinitely.

Please help.

can you check the logs? upgrade_wizard.log, suitecrm.log, apache logs

best regards
