Reset wordpress Premissions on Linux

 When you try to update wordpress or install /update a plugin and fail to do so, it means you need to reset the folders and files permissions on your server. You can bulk fix the problem by updating the permissions of the directories and files in your web host location: cd /home/www/yourdomainfolder/  In your web directory root run the below command: find . -type d -exec chmod 755 {} \; This would change the access permission to all folders to rwx r_x r_x Now time to change the files permissions to -rw-r--r--  find . -type f -exec chmod 644 {} \; The Directories and files are now reset to the default. If you still face a problem it means you need to change the owner of the folders and files.

Tracking mobile users on Confluence while using Refinedwiki mobile theme is not possible or straightforward using theme configuration. I found a work around that will track users on Google Analytics smoothly. Please follow the below steps: Create a js file, call is analytics.js with the analytics script code, it should look something similar to the below:   (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){   (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),   m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)   })(window,document,'script','//www.google-analytics.com/analytics.js','ga');   ga('create', ' UA-XXXXXX ', 'auto');   ga('set', 'userId',AJS.Data.get("remote-user")); // Set the user ID using signed-in user_id.    ga('send', 'pageview'); Save your script on confluence server confluenceInstall

linux Server out of Space

You could find your VPS out of space all the sudden especially if you are enabling logging for your website or web apps. First you need to know which directory is taking most of the size, then you can eliminate the problem or ask to increase disk place: Go to the root of your vps by typing on ur shell:# cd / Run: #sudo du -h --max-depth=1 Note which directories are using a lot of disk space . cd into one of the big directories. Run #ls -l to see which files are using a lot of space . Delete any you don't need.
