Hello!

I’m having troubles after Mailer Extension installation. I wonder if any  
extension or gem that I don’t have is required. Attached is a file with  
the error I get when trying to boot mongrel.

In this instance I’ve also tried to install the Blog extension.

This one is my gem list

actionmailer (2.3.2)  
actionpack (2.3.2)  
activerecord (2.3.2)  
activeresource (2.3.2)  
activesupport (2.3.2)  
cgi\_multipart\_eof\_fix (2.5.0)  
daemons (1.0.10)  
fastthread (1.0.7)  
gem\_plugin (0.2.3)  
linecache (0.43)  
mongrel (1.1.5)  
mysql (2.7)  
radiant (0.8.0)  
rails (2.3.2)  
rake (0.8.7)  
RedCloth (4.2.2)  
ruby-debug-base (0.10.3)  
ruby-debug-ide (0.4.5)  
rubygems-update (1.3.4)  
sqlite3-ruby (1.2.4)

Thanks very much,  
Paula

I’ve worked around this issue and fixed it installing Page\_attachment  
extension. Now mongrell works good, but several issues appeared inside  
the admin backend. When I want to create a page or access a page from  
the admin it display the following mistake:

Mysql::Error: Table ‘radiant\_production.page\_attachments’ doesn’t exist:  
SHOW FIELDS FROM `page_attachments`

Thanks very much for your help!
