I can edit this, as well. In fact, it's a copy of the page I'm trying to edit on the LyX Wiki.
Ok (also expected, and yes, I simply copied the InstantPreviwe-page to a different wiki server -- www.pmichaud.com)
So it does not appear to be a question of the amount of text.
Actually, I think it *is* a matter of the amount of text. The page above was on a different server.
So you think the text quantity issue is tied to a specific server (as opposed to a specific client, or client configuration, or failure to make an appropriate propitiation to the gods before clicking "save")?
Here's a link to another page on the lyx wiki with lots of text (you shouldn't be able to edit this either):
http://wiki.lyx.org/pmwiki.php/SiteTest/LotsOfText
Just for fun, try and remove more and more text from this page and suddenly you should be able to save it -- not that this is any practical solution....
You're right. Deleting paragraph 5 did not do the job, but deleting 4 and 5 let me save it.
Do you have some router/gateway at home that might be involved in this? As I've said before, I've had this problem intermittently and I have a DI-714 (I think). Or maybe it's some router/gateway in your network path?
I do this from my office (Ethernet to OC3 (?) link to regional net). I have a personal firewall on my office PC, and there are allegedly firewalls in place between my building and our campus and between our campus and Out There. However, the building firewall (allegedly) only filters inbound traffic, and I believe the same holds for the campus firewall. So the edited page should be reaching the server.
Using a browser on a remote system did work. I have no idea why, of course.
This seems to be a problem that only happens when you: * Do the save from some network (unknown what the characteristics are) * The page contains more text than some unknown limit
Maybe there is something in the network path that doesn't like posting data over a certain size?
Highly unlikely in my case. The server I used for a successful remote post is on the same network segment as my office PC, so the successful and unsucessful traffic should have followed pretty much identical routes. The server has a static IP and my PC gets its IP address by DHCP, but that seems unlikely to explain the difference.
Hmm. Just edited the page successfully from two PCs across the hall from my office (same segment). One was Win 98, the other Win XP (same as my office), so the OS is not the differentiator. (Incidentally, FYI, the Wiki pages do not display correctly on Netscape 4.76, perhaps indicating a problem with CSS support in an older browser.)
Aha! (Or perhaps I should say "Aha??") I turned off my firewall momentarily (scary thing to do here), and an edit went through just fine. Stranger still, I then turned the firewall back on, and I can still edit the test page.
I can't find anything in the firewall log with respect to traffic to/from wiki.lyx.org. However, there is an entry with a similar IP address (maps to tott.linpro.no). It's about the right time frame for one of my unsuccessful edit attempts (prior to turning the firewall off), and it indicates that the firewall blocked 19 ICMP Type 3 (Destination Unreachable) packets from tott.linpro.no, apparently in response to traffic I sent.
Ok, this is getting a bit stochastic. I closed the browser and restarted it, then (with the firewall on) edited the LotsOfText page and tried to save. The browser hung, and the firewall reported a bunch of ICMP 3 packets from tott.linpro.no. Fine. I then ran netstat to check network connections, tried another edit (without shutting down the firewall, without restarting the browser) and the edit went through (!?). Then I tried another edit, and it failed, but I got no new ICMP packets from tott.linpro.no. And then another attempt succeeded.
If you can find any useful diagnostic information in all that, more power to you!
