I cannot install using the automatic installer. I get out of memory errors
The PDF plugin is rather large. So some hosting environments will not allow you to use the automatic installer from Settings > Upgrade.
In the zip file you downloaded from Codecanyon you will see a “plugin_pdf” folder. Please extract this folder and manually upload this folder to the “includes/” folder on your system.
You should see all the other “plugin_*” folders in here, just add the “plugin_pdf” and away you go.
Once that is uploaded, head back to your Settings > Upgrade window and try again. This should fix any out of memory problems.
