Error after migration

[Ibitoyei]

Please help me out, I've been battling with this issue for some weeks now, I moved to another web hosting and since the I've been getting this error "Fatal error: Class 'JLog' not found in /home/vhosts/www.dinspirate.ml/libraries/joomla/error/error.php on line 352" I've really tried resolving the issue but I am not able to... I'll appreciate it if someone can help me out. Thanks.

Use the files from the Joomla full package to overwrite those on the server

After overwriting the files, the error changed to "Fatal error: Class 'JDate' not found in /home/vhosts/www.dinspirate.ml/libraries/joomla/log/entry.php on line 99"

The missing class is defined in the file libraries/joomla/utilities/date.php, which may be corrupted or not where it should be. Copy it from the installation archive to the server and that should fix the last error.
