Common mistakes and solutions when setting up WordPress

The move from, shared hosting to personal VPS and the issues associated.

 

I moved the blog.alexcollie.com over to a personal VPS, which allowed for a greater deal of customisation.

However I was plagued  with issues. Like the php code not being able to modify the WordPress files. All of these challenges are simply solved, but do take a lot of googling.

Common mistakes I made

This error with trying to connect Jetpack

jetpack Please contact your hosting provider to enable PHP’s XML extension.

It seemed like no one else had suffered the same issue.

The solution was really easy just do.(php 7 code)

apt install php-xml

or depending on apt version

apt-get install php-xml

Every time you try and install a or plugin or upload an image or post it said

To perform the requested action, WordPress needs to access your web server. Please enter your FTP credentials to proceed. If you do not remember your credentials, you should contact your web host.

This was a permissions issue were the php code did not have the rights to modify any of the files. Again it a really easy fix

chown -Rf www-data.www-data /var/www/html/

Just change ‘html’ to where the WordPress file is located.

I can think this page for this solution

 

When I tried to crop img inside WordPress it could run into errors.

sudo apt-get install php-gd

or

sudo apt install php-gd

This adds a library which allows php to crop images.

 

Despite all of these errors. Linux/GNU is amazing.
