Download the .zip with the new plugin version from the CodeCanyon > Downloads page to your computer.

Now you need to upload MapSVG to your WordPress website. There are 2 ways to do this:

1. Upload via WordPress Admin

Open your WordPress admin panel, go to Plugins. Find MapSVG, click Deactivate. When the page reloads, find MapSVG again and click Delete. Now go to Plugins > Add new > Upload. Upload .zip with the plugin, click Activate.

Please note that map settings and custom uploaded SVG files will not be lost even if you delete the plugin. But if you uploaded custom marker images to mapsvg/markers folder they will be lost with this method of updating. You'll need to upload them again or use the second method of updating shown below that doesn't delete the mapsvg/ folder.

If you see "The link has expired" error – this usually means that you need to increase max. uploading file size in php.ini settings:
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

2. Upload via FTP

An alternative, in case the WordPress Admin Upload does not work: unzip the file that you downloaded from CodeCanyon. Open your WordPress installation folder using any FTP manager: it could be Cyberduck, FileZilla, Total Commander. Go to the wp-content/plugins/ folder and upload the mapsvg folder you previously unzipped, overwriting the existing wp-content/plugins/mapsvg folder and all files inside of it.

Now in your WordPress admin panel go to Plugins > Installed plugins, find MapSVG and click Activate. MapSVG will appear in the main WP Menu on the left.
