HOW TO INSTALL OR UPDATE A GPL THEME OR PLUGIN
All GPL themes and plugins are easily installed & updated as follows:
IMPORTANT: We recommend installing the plugin “Easy Theme and Plugin Upgrades” before you use GPL items. You can download it for free by clicking here. You can also search it from your control panel within the WordPress free plugin repository as a new plugin to add.
WordPress has a built-in feature to install themes and plugins by supplying a zip file. Unfortunately, you cannot upgrade a theme or plugin using the same process. Instead, WordPress will say “destination already exists” when trying to upgrade using a zip file and will fail to upgrade the theme or plugin. Easy Theme and Plugin Upgrades fixes this limitation in WordPress by automatically upgrading the theme or plugin if it already exists.
While upgrading, a backup copy of the old theme or plugin is first created. This allows you to install the old version in case of problems with the new version. By installing and activating this Plugin you can avoid update conflicts if you already have a previous version of the product to update.
DO YOU HAVE AN ERROR WHEN INSTALLING?
It is very important that you do not forget that some products (for example those of Themeforest and Codecanyon) in many occasions come in a double compression, that is to say, a zip file inside another zip.
Check your product before installing to see if this is the case because if it is, the main zip you downloaded will not be the installable one, which will lead you to installation errors like the one in the CSS stylesheet for example.
If you upload the main zip and receive an error, it is most likely because the main zip is not the installable one. Unzip the main zip and you will find the installable zip inside.
Remember that the Plugins, Extensions and Addons are always uploaded in the Plugins area. And the themes always in the Appearance area.
You MUST make sure that your WordPress installation meets the minimum requirements which are as follows:
Before purchasing a subscription, on the website, make sure your hosting meets the following minimum requirements for WordPress:
Apache or NGINX based web server with 128MB of RAM
PHP version 5.6 or 7.0
MySQL version 5.6+ or MariaDB version 10.0+
Apache Module mod_rewrite
To avoid errors during product installation, make sure you are using the correct PHP settings on your web server:
max_execution_time = 600;
max_input_vars = 5000;
memory_limit = 256M;
post_max_size = 128M;
upload_max_filesize = 128M;
For themes with a weight of more than 200 megabytes (which include the different templates) it is necessary that you make your upload through FTP.
