warning: preg_replace() [function.preg-replace]: compilation failed: unknown option bit(s) set @ offset -1 in /home/internet/public_html/wp-includes/shortcodes.php on line 258 [contact-form-7 404 "not found"]

please me fix it.

thanks read.

looks problem in contact form 7 plugin.

1: go wp admin interface > plugins , disable contact form 7

what we're doing here trying isolate problem. seeing whether issue contact form 7 plugin, or else.

2: reload affected page

if error no longer present, problem inside plugin. (go #3.) if error still present, problem not inside plugin, if update error message in question new message seen, help.

3: update plugin

if there update available plugin, upgrade it, re-activate , retest it.

4: if it's still problem

the error message suggesting parameter being handled preg_replace() call incorrect. case of looking closely @ each instance contact form 7 shortcode used, function associated shortcode, try , see going wrong.

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
