Gallery Upgrade Error: Some files and or directories in your storage directory are not writeable by the webserver user
While upgrading gallery, you may come across with the following error while doing Step 2: System Checks
Error: Some files and or directories in your storage directory are not writeable by the webserver user.
Run chown -R webserverUser /home/abcduser/public_html/gallery/g2data/
OR run chmod -R 777 /home/abcduser/public_html/gallery/g2data/.
Even if you change the permissions / ownerships for g2data, you will get the same error.
This occurs when the versions.dat file is missing in the storage folder (g2data folder). You can create one by entering the following:
1.2.0.6
2.2
The second line is not significant. But you should enter the first line correctly. It must be the version of the g2 core module installed in the current gallery installation. You can get the version by executing this query in the MySQL database used by gallery.
SELECT g_parameterValue FROM g2_PluginParameterMap WHERE g_pluginId = ‘core’ and
g_parameterName = ‘_version’;
The output will be something like this:
+——————+
| g_parameterValue |
+——————+
| 1.2.0.6 |
+——————+
Once you create the versions.dat file, run the upgrade/index.php and run “System Checks”.
