OpenX upgrade results in plugin errors

This does not look like an error in PEAR or its libraries, but with OpenX. Ask in their support forums.

I was just having the same issue (as I had had in the past). For the first time ever, though, I just managed to have a smooth upgrade to 2.8.9.

What I did:

MAKE SURE TO DO ANY BACKUPS AND TEST-RUN THE PROCESS AND DOUBLE CHECK FOR ANY POSSIBLE ERRORS. USE THESE EXPLANATIONS AT YOUR OWN RISK

[!] OpenX requires a file-path to the old installation in order to complete the upgrade (it basically checks the plugins in the old version and then re-installs them in the new version). So you should always upgrade by having a clean/new installation directory, and not replace the current installation with the new openx files.

• create new database (openx_new) and give the database user permissionsto the new database (don't forget to give access to LOCK TABLEs)
• dump the current database and load into the new one

mysqldump -uUSER -pPASSWORD openxdb_old –skip-lock-tables > FILE.sql mysql -uUSER -pPASSWORD openxdb_new < FILE.sql

• unzip the new openx files in, eg, /openx_new
• copy the configuration file(s) and any banner/image files you may have from the old to the new directory
• adjust the configuration file in the new directory so it points to the new database created above (openxdb_new)

Here comes the switch:

• flip the directories: mv /openx /openx_old and mv /openx_new /openx ; now the new files are in the directory /openx and the old ones in /openx_old.
• go to the admin page of openx (eg, http://www.example.org/openx). After logging in, the installation/upgrading process should kick in.
• it may ask for some minor changes in the file permissions; fix them.
• eventually, it will ask for the directory where the previousversion was installed; point to the "/openx_old" directorymentioned above. This will cause OpenX to check the pluginsand re-install them.

You're done. Hopefully.

The article offers a way to avoid any downtime, I went ahead with just a few seconds of dowtime and 10 minutes of lost statistics.

Don’t worry about this problem, I also lacked the same problem, at that time my friend refers to use the openxmods.com plugins, they are different types and also all plugins are develops using latest technologies and development of custom plugins is also possible in openxmods.com. All plugins are easy to install.

If you interest to using latest openx ad server choose openxmods.com plugins. I assure that 100% confidentially, and also efficiency.
