Solve "The link you followed has expired" Problem in Wordpress

We love wordpress, as it makes our live easier. But sometimes we face issues while setting up website. In this post I am going to talk about such error installing a new theme.

How problem generates:

When we try to install our theme via appearance -> themes -> add new, we get following message:
The link you followed has expired.

Cause of the problem:

Upload max size or maximum memory on our server are not well configured.

Solution of the problem:

We have to set Upload max size or maximum memory on our server as below:

memory_limit = 256
upload_max_size = 64M
post_max_size = 64M
upload_max_filesize = 64M
max_execution_time = 300
max_input_time = 1000

You can do that via contacting host company or you can do it yourselves by editing .htaccess file. Follow below steps to do that:

• Access your WordPress installation.
• In root directory, you will find your .htaccess file.
• Edit it to add below lines at the end:

php_value memory_limit 256M
php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 1000
