For our arabic website, the Title can be too long so I changed the News.Title to be LongText in web.config and using a script I created with the help of this link
I read-deleted-resaved all item & the News title is saved in LongText instead of Short Text.
The problem though is that in Sitefinity saves in LongText but it doesn't except more characters and I get this exception. Value for property Url is too long. Maximun length is 256
If I remove any extra text, the item is saved properly to the LongText field.
I want more characters to be saved and thats why I changed it to LongText in the first place.
I'll appreciate the help, if the question is not too clear then let me know.
