 * Hello everyone,
 * I just set up my blog using wordpress (www.tzakas.com/blog) and I have the following
   problem.
    I can make a post in plain text, but I cannot add any links, or use
   bold/italic fonts, etc, so I came to the conclusion that I cannot use HTML code.
   I should note, that I installed WordPress (2.6.1) using Fantastico (within CPanel).
 * I tried editing my post from another computer but that didn’t help.
 * I even removed WordPress and installed Drupal and I have the exact same issue!
   I am now back with wordpress and I think the problem lies with the host (although
   I don’t have any other clue).
 * Any ideas/suggestions?
 * Thx
    Argyrios

 * Problem fixed. It had to do with ModSecurity. Here’s an explanation I found on-
   line:
 * _ModSecurity is an open source embeddable web application firewall, or intrusion
   detection and prevention engine for web applications. ModSecurity provides protection
   from a range of attacks against web applications and allows for HTTP traffic 
   monitoring and real-time analysis with no changes to existing infrastructure,
   by operating as an Apache Web server module mod\_security or standalone, and 
   thus increase web application security. However, misconfigured or overly strict
   rule sets, ModSecurity may cause your website to return various errors such as
   HTTP 403 Forbidden error or access denied error, login problems, or HTTP 412 
   Precondition Failed error, or HTTP 406 Not Acceptable error and other false positive
   symptoms._
 * To make matter worse, the configuration of ModSecurity rules and filters have
   to be done manually. Although there are free predefined certified rule set which
   can be used with ModSecurity out of the box, however the rule sets may be not
   suitable for each and every environment and may interfere with the operation 
   of websites or blogs, and customizing and modifying the rules may be too sophisticated
   or complicated for some users. And for some websites that hosted on shared hosting
   service, the mod_security may be enable by default without options. So in this
   case, the best solution or workaround for mod security related issues is to disable
   mod_security filtering and rules.
