[TYPO3-english] Class 't3lib_SpriteManager' not found

[joydeep at infoservices.in]

Hello list,

I have migrated a typo3 site running on version 4.2.8 to a different
server. Complete file level copy.
The frontend is running well. But when try to log into the BE, it throws
an error as

` ` ` `
Fatal error: Class 't3lib_SpriteManager' not found in
/srv/www/htdocs/xxxxx/typo3conf/temp_CACHED_psd13d_ext_tables.php on line
2752
` ` ` `

I have manually deleted the cache files from server. Still the same error.

Any clue please ?

Thanks
