Is there a limit on the amount of text? I want to publish an article in the blog. There was a problem. If the text is big enough the page is shown empty.
You mean, when you save the page from the admin panel, it saves properly, but the website page is broken? ... and only if the TEXT is long enough? How long is it? On your /check/ page, I think it might be related to the max_input_vars limit, which might block posting data with more than 1000 characters ....
