+ | This could be a trade off between security and usability, although it is completely possible to have your DokuWiki work with mod_security, | ||
+ | |||
+ | On Apache2, you can disable mod_security for a specific path inside the VirtualHost block inside your site files (for instance, in / | ||

+ | Changing the setting on that one rule was done. A warning was given on removing mod_security: | ||
+ | > While many sites (such as forums) would need this rule enabled to prevent spamming on their forums and usually limit the number of urls a post can have, sites that have posts with a large number of links in them (like wikis) can easily trigger this rule and may need it disabled. | ||
+ | > Mod_security is m to the type of attack that the particular rule prevents, but disabling one rule is better then disabling all. | ||

+ | A little more problem determination gave a better solution. |
