The last 2 RSSeo! revisions have brought among new functionalities, some important crawler changes: the ability to use RSSeo! without loopback connections.
What does it mean?
To be able to analyze site pages, RSSeo! must first crawl your website. In order to perform this task, it requires at least one of the following functions to be enabled: cURL , fsockopen , fopen , file_get_contents. Most hosting providers impose some restrictions in using these, only allowing one of them and loopback connections. The last one (loopback), basically implies that a script can't get the content of page if the call to the function is made from the same host. You can imagine that this seriously affected the RSSeo! functionality, preventing the proper meta data management.
Beginning with RSSeo rev. 7 and 8, there are 2 more options available to run RSSeo!, besides using the loopback connections: connection via a configured proxy server and PHP exec function.
Option 1: Loopback connections via cURL , fsockopen , fopen or file_get_contents
(available for all RSSeo! revisions)
This is part of the RSSeo! minimum requirements: to be able to run RSSeo! you must have enabled at least one of the following functions cURL , fsockopen , fopen , file_get_contents.
In case your hosting provider doesn't allow loopback connections, then head to the second option.
