I'm running a multisite installation with an English version of the site and a Spanish version of the site. The Landing Pages plugin is installed for use on both sites. The English site is at domain.com and the Spanish site is at domain.com/es.
I can create a landing page on the English site without any problems.
When I create a Spanish landing page, I can view it using the preview option before it is published. However, when I setup the permalink and publish the page I get a 404 error. For example, I can preview the post with a link similar to domain.com/es/?post_type=landing-page&p=526. However, I get a 404 error when I publish the post and set the permalink to domain.com/es/test.
Any help is appreciated.
