Hi,

I just compiled the source code of Mojo 2.2 and when I try to run it I get this error. I am using MySql and I did all settings in order to use it. I don;t know what to do...please help.

I used it before and it worked, the MySql database remained the same(It has the update for 2.2 ver). I am a little bit confused...

Thanks Joe for all.

I have just deleted old database and recreated new one. It works now until
Welcome to mojoPortal Setup
No Sites have been created yet, click the button to create initial site data.

But when I click the button I get this:#42S22Unknown column 'LdapDomain' in 'field list' at MySql.Data.MySqlClient.PacketReader.CheckForError() in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\PacketReader.cs:line 149 at MySql.Data.MySqlClient.PacketReader.ReadHeader() in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\PacketReader.cs:line 117 at MySql.Data.MySqlClient.PacketReader.OpenPacket() in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\PacketReader.cs:line 131 at MySql.Data.MySqlClient.NativeDriver.ReadResult(Int64& affectedRows, Int64& lastInsertId) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\NativeDriver.cs:line 369 at MySql.Data.MySqlClient.CommandResult.ReadNextResult(Boolean isFirst) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\CommandResult.cs:line 125 at MySql.Data.MySqlClient.CommandResult..ctor(Driver d, Boolean isBinary) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\CommandResult.cs:line 52 at MySql.Data.MySqlClient.NativeDriver.SendQuery(Byte[] bytes, Int32 length, Boolean consume) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\NativeDriver.cs:line 330 at MySql.Data.MySqlClient.MySqlCommand.GetNextResultSet(MySqlDataReader reader) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\command.cs:line 295 at MySql.Data.MySqlClient.MySqlDataReader.NextResult() in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\datareader.cs:line 683 at MySql.Data.MySqlClient.MySqlCommand.ExecuteReader(CommandBehavior behavior) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\command.cs:line 406 at MySql.Data.MySqlClient.MySqlCommand.ExecuteReader() in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\command.cs:line 376 at MySql.Data.MySqlClient.MySqlCommand.ExecuteScalar() in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\command.cs:line 419 at MySql.Data.MySqlClient.MySqlHelper.ExecuteScalar(MySqlConnection connection, String commandText, MySqlParameter[] commandParameters) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\MySqlHelper.cs:line 354 at MySql.Data.MySqlClient.MySqlHelper.ExecuteScalar(String connectionString, String commandText, MySqlParameter[] commandParameters) in D:\@Work\Mojo 2.2\mojoportal\MySQLConnector\MySqlClient\MySqlHelper.cs:line 318 at mojoPortal.Data.dbPortal.SiteSettings_Create(Guid siteGuid, String siteName, String skin, String logo, String icon, Boolean allowNewRegistration, Boolean allowUserSkins, Boolean allowPageSkins, Boolean allowHideMenuOnPages, Boolean useSecureRegistration, Boolean useSSLOnAllPages, String defaultPageKeywords, String defaultPageDescription, String defaultPageEncoding, String defaultAdditionalMetaTags, Boolean isServerAdminSite, Boolean useLdapAuth, Boolean autoCreateLDAPUserOnFirstLogin, String ldapServer, Int32 ldapPort, String ldapDomain, String ldapRootDN, String ldapUserDNKey, Boolean allowUserFullNameChange, Boolean useEmailForLogin, Boolean reallyDeleteUsers, String editorSkin, String defaultFriendlyUrlPattern, Boolean enableMyPageFeature) in D:\@Work\Mojo 2.2\mojoportal\MySQLData\dbPortal.cs:line 1405 at mojoPortal.Business.SiteSettings.Create() in D:\@Work\Mojo 2.2\mojoportal\Business\SiteSettings.cs:line 683 at mojoPortal.Business.SiteSettings.Save() in D:\@Work\Mojo 2.2\mojoportal\Business\SiteSettings.cs:line 807 at mojoPortal.Business.WebHelpers.mojoSetup.CreateInitialData() in D:\@Work\Mojo 2.2\mojoportal\mojoPortal.Business.WebHelpers\mojoSetup.cs:line 112 at mojoPortal.Web.UI.Pages.SetupHome.btnCreateInitialData_Click(Object sender, EventArgs e) in D:\@Work\Mojo 2.2\mojoportal\Web\Setup\Default.aspx.cs:line 139
Thank you again for all the help!

ok Joe, thanks.

Cristian

Something happens because I got an error similar to

#42S22Unknown column 'LdapDomain' in 'field list' at MySql.Data.MySqlClient.PacketReader.CheckForError()
....

but telling that `AllowBrowserCache`  does not have a default value. I added a default value for  `AllowBrowserCache` (`AllowBrowserCache` bit NOT NULL default 1) and now it works.
I didn't download 2.2.1.5 release files, but I will.

Thanks again for all the help!
I want to thank you also for the great job you do with Mojo.
