Smartblobs error in Web Datablade

Hi everyone, I get this error message "Exception from Informix: XIX000 -9810:Smartblobs error." when i tried to edit the source of web pages that I have created previously using Informix App Pages Builder (Web Datablade) via web bowser (IE or Netscape). When I do a SQL Select from the web pages from the webpages table, I encountered the same error message. However, the count of the webpages table shown the correct number of records (web pages) in there when i do a Select Count(*) from webpages. Meaning the records is in there, correct me if I'm wrong. Why couldn't I view/edit the web pages stored in the webpages table from the App Pages Builder (Web Datablade)? What should I do to correct it? Is there any alternative to access the App Pages Builder (Web Datablade) other than via browser (IE or Netscape)? what other Infromix frontend product can i use in replace of App Pages Builder (Web Datablade) ? HW: IUS 9.14, Irix 6.5. Many Thanks, YFWoi
