Even more info. I have two users, both “Editors”. One can edit a post, the other can not. The latter sees a blank page.

The difference is that the working user has a specific language selected (Nederlands-Belgi?). The non-working user has “site default” selected. Which is “Nederlands”

When I change the language of the non working to a specific language (can also be “Nederlands”), it works. Hope this helps in debugging this problem. So it’s not a problem with a specific language I think, it’s a problem with the option “site default”.

More info regarding my issue: when both The Event Calendar (6.3.5) and W3 Total Cache (2.7.0) are active then an “Editor” can not edit a post or page. They see a totally blank page. Content-length:0. In the logs there is the output buffering entry.

An admin cán edit any page or post.

If I disable either W3cache or The Event Calendar, it works again. So these two plugins are not working together at this time in these specific versions.

I’m having a similar problem, might be not exactly the same, but it’s also related to output buffering. The result is the same: some users get a totally blank page when trying to edit a post. There is a logline on my server:

mod_proxy_fcgi.c(887): [client XXX.XXX.XXX.XXX:0] AH01071: Got error ‘PHP message: PHP Fatal error: str_replace(): Cannot use output buffering in output buffering display handlers in /data/sites/web/…/www/wp-content/plugins/w3-total-cache/UserExperience_LazyLoad_Plugin.php on line 69’
