Steps to Reproduce:
- Create a simple form with Special:CreateForm or by editing source. I.e this one:
<noinclude>
This is the "Test3" form.
To create a page with this form, enter the page name below;
if a page with that name already exists, you will be sent to a form to edit that page.
{{#forminput:form=Test3}}
</noinclude><includeonly>
<div id="wikiPreview" style="display: none; padding-bottom: 25px; margin-bottom: 25px; border-bottom: 1px solid #AAAAAA;"></div>
==section1==
{{{section|section1|level=2}}}
'''Free text:'''
{{{standard input|free text|rows=10}}}
{{{standard input|summary}}}
{{{standard input|minor edit}}} {{{standard input|watch}}}
{{{standard input|save}}} {{{standard input|preview}}} {{{standard input|changes}}} {{{standard input|cancel}}}
</includeonly>- try to create a page with this form. Go to Form:Test3 and give a name i. e. test31, then click "Create and Edit" button
Actual Results:
a site with URL /index.php/Special:FormStart?form=Test3&page_name=test31 opens and only a animated loading.gif appears on the blank white page. No errors at all.
The source of the opened site:
<html><head></head><body><p style="position: absolute; left: 45%; top: 45%;"><img src="/extensions/PageForms/skins/loading.gif"></p> </body></html>
Expected Results:
a new page from page form should be created.
