I think I'm having exactly the same problem. Whenever I try to put a large chunk of content, I get a 403 error when submitting the page. And for whatever reason, this only occurs when the text is several paragraphs down the page and it includes the word "from". I know, sounds crazy, right? Here's the text I'm using:
With the enthusiastic support of Jerome Hill, the Committee, consisting of P. Adams Sitney, Peter Kubelka, James Broughton, Ken Kelman and myself and for a brief period Stan Brakhage began its work. During the following few years it held numerous and lengthy selection sessions, compiling the first Essential Cinema Repertory collection consisting of about 330 titles.
But fate had other plans for us. In February 1973 Jerome Hill died. The Avon Foundation, Jerome's foundation behind the Anthology project, which had built a special, Invisible Cinema theater, designed by Peter Kubelka, and had paid for the acquisition of all the prints voted into the Essential Cinema collection, and the running of Anthology was taken over by people who did not share Jerome's vision. All funding to the Anthology project was cut off. Anthology had to move <strong>from</strong> the 425 Lafayette Street location, first to 80 Wooster Street, then to 491 Broadway, and then to its present location.
It also happens with this text:
The cinematheques of the world generally collect and show the multiple manifestations of film: as document, history, industry, mass communication... Anthology Film Archives is the first film museum exclusively devoted to the film as an art. What are the essentials of the film experience? Which films embody the heights of the art of cinema? The creation of Anthology Film Archives has been an ambitious attempt to provide answers to these questions; the first of which is physical - to construct a theater in which films can be seen under the best conditions; and second critical - to define the art of film in terms of selected works which indicate its essences and parameters.
One of the guiding principles of this new film museum is that a great film must be seen many times. For that reason the entire collection will be presented in repeated cycles. With three different programs each day, an anthology of one hundred programs (approximately equivalent to our present collection) can be repeated monthly. In this way frequent periodic viewing will be possible for the dedicated spectator. The cycle will also provide a unique opportunity for students of the medium to see a concentrated history of the art of film within a period of four or five weeks. One would have to travel extensively and spend a few years in film museums to acquire the cinematic education of equal magnitude.

AN UPDATE: Our present physical and financial conditions do not permit us to screen the Essential Cinema Repertory as it was initially presented. Our projection is still far <strong>from</strong> perfect, and 3 programs per day is a far dream. But the Repertory itself is intact and it will remain so, a heroic statement of the art of Cinema.
