Hi,

I updated concrete on one of my sites today to the latest version. Everything looked fine at first, no suddenly I get this on the front page:

An unexpected error occurred.
mysqlt error: [1054: Unknown column 'Blocks.btCachedBlockRecord' in 'field list'] in EXECUTE("select CollectionVersionBlocks.isOriginal, Blocks.btCachedBlockRecord, BlockTypes.pkgID, CollectionVersionBlocks.cbOverrideAreaPermissions, CollectionVersionBlocks.cbDisplayOrder, Blocks.bIsActive, Blocks.bID, Blocks.btID, bName, bDateAdded, bDateModified, bFilename, btHandle, Blocks.uID from CollectionVersionBlocks inner join Blocks on (CollectionVersionBlocks.bID = Blocks.bID) inner join BlockTypes on (Blocks.btID = BlockTypes.btID) where CollectionVersionBlocks.arHandle = 'sub-menu' and CollectionVersionBlocks.cID = '1' and (CollectionVersionBlocks.cvID = '61' or CollectionVersionBlocks.cbIncludeAll=1) and CollectionVersionBlocks.bID = '256'")

Obviously I tried to restore to a backup I made just before I updated and I get this:

Fatal error: Uncaught exception 'ADODB_Exception' with message 'mysqlt error: [2006: MySQL server has gone away] in EXECUTE("SELECT TABLE_NAME, CASE WHEN TABLE_TYPE = 'VIEW' THEN 'V' ELSE 'T' END FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA=SCHEMA()") ' in E:\WebSites\roller-skis.com\Html\updates\concrete5.6.2.1\concrete\libraries\3rdparty\adodb\adodb-exceptions.inc.php:78 Stack trace: #0 E:\WebSites\roller-skis.com\Html\updates\concrete5.6.2.1\concrete\libraries\3rdparty\adodb\adodb.inc.php(1074): adodb_throw('mysqlt', 'EXECUTE', 2006, 'MySQL server ha...', 'SELECT TABLE_NA...', false, Object(ADODB_mysqlt)) #1 E:\WebSites\roller-skis.com\Html\updates\concrete5.6.2.1\concrete\libraries\3rdparty\adodb\adodb.inc.php(1049): ADOConnection->_Execute('SELECT TABLE_NA...', false) #2 E:\WebSites\roller-skis.com\Html\updates\concrete5.6.2.1\concrete\libraries\3rdparty\adodb\adodb.inc.php(2334): ADOConnection->Execute('SELECT TABLE_NA...') #3 E:\WebSites\roller-skis.com\Html\updates\concrete5.6.2.1\concrete\libraries\3rdparty\ in E:\WebSites\roller-skis.com\Html\updates\concrete5.6.2.1\concrete\libraries\3rdparty\adodb\adodb-exceptions.inc.php on line 78

Can anyone help! This is a live site :O

Thanks
