Mantis Bug Tracker - Forums

Hello,
I upgraded Mantis version 1.2.19 to 2.10 with the following:
mysql 5.7.20 /php version 7.0.27 installed ok , I can open matis application; upload files, view files uploded, but when i try to open attached files & after download them I recieve message error file corrupte,domaged...(see attached file).
I checked my mantis installation with /admin/check/index.php (see attached file), I've 2 environment prod & test, I installes new mantis version on test, I migrated data from old enviroment to the new one by using mysql import data.
the new attachement created with the new mantis 2.10 work, but the old one created with the old version not work after migration to the new mantis version,my impression is that the attachments work in general but only for the new tickets like, did anything go wrong with the migration of the attachments along with the tickets?

help please?

Hello,
the old ticket with attachment created with the old version not work after migration to the new mantis version,my impression is that the attachments work in general but only for the new tickets, did anything go wrong with the migration of the attachments along with the tickets?
can you help me please?

Are your attachments stored in database or on filesystem?

thank you for your feedback...the attachment stored in database

Have a look at database table mantis_bug_file_table and check if there is any obvious difference between old and new attachments.

They are stored in mantis_bug_file_table

The question was, if there is any difference between old and new ones.

You could also an attachment from your old installation, attach it on the new installation and check any columns of the table for differences.

Were you able to find a solution, I have exactly the same problem I did a migration from Mantis 1.2.20 to Mantis 2.10.0.

My backup datatase have a different collation latin1_swedish_ci. I tried to update the database to UTF8 using the following query but it did not help
ALTER DATABASE bugtracker CHARACTER SET utf8 COLLATE utf8_unicode_ci;

I tried to compare the old and new attachement and the only difference if the file type "image/png;" for the old attachement and ""image/png; charset = binary". The page looks like this:

Hi Guys,

I solved this issue.
My issue was Images, PDF was not downloading (Old).
Problem was old files were transferred from my local to server using filezilla with transfer mode as "Auto".
After researching, I transferred again the attachment files only using transfer mode as "Binary".
Now images and Pdf's are downloading.

Thanks all.

I had this problem when upgrading from 2.8 to 2.21. For me the solution was to add the following line to php.ini under the section [ExtensionList]:

extension=php_fileinfo.dll
