When change template : Your browser sent a request that this server could not underst

[abdobasha2004]

when try to change forumhome template in certain style I get :

Bad Request

Your browser sent a request that this server could not understand.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

however the rest of styles and templates of this style are changed normally

That usually happens when the URL that goes to the browser is misspelled or malformed so the request doesn't match the standard syntax. Check the browser input box to see it you can see a misspelling or something when you try to bring up that page.

I am sure of spelling
I come to this error after choosing edit templates from my admin cp
so there is no error in writing

[Marco van Herwaarden]

Is this only with a specific edit (can you save the template without any changes)?

Also this could be caused by mod_security or Suhosin, is any of thatinstalled at your server?

[abdobasha2004]

it is for specific template of specific style, any edit I get that message (not specific edit)
I am not using one of above mods

[Marco van Herwaarden]

Those are not vB modifications (just in case you misunderstood that).

Can you try to up your PHP memory limit?

up your PHP memory limit?

how to do that?

by the way I noticed in general large templates as showthread and forumhome cannot be edited
small templates as postbit and tagbit are edited normally

Can you go to vbulletin options --> show all settings and try to save all settings at once, does that work?

If it doesn't please check and verify that your server is running modsecurity, you can verify that its running modsecurity by viewing your php info, it should be listed under apache2handlers Loaded Modules box.

Example:

mod_env mod_mime mod_security2 mod_negotiation mod_php5 mod_rewrite mod_setenvif mod_status mod_unique_id

[abdobasha2004]

no it does not

Forbidden

You don't have permission to access /vb/admincp/options.php on this server.

how to do that

by viewing your php info, it should be listed under apache2handlers Loaded Modules box.

I am running admin panel
how to know apache2handelers?

thanks for help
