Thread:Project:Support desk/Page wont save with cimetidine

Mediawiki 1.21.1

PHP 5.3.25

Mysql 5.5.31

I have experienced a curious problem when submitting a page that contains the string cimetidine. The page is not saved and browser redirected to the Main Page.

I used the sandbox and incrementally created the problem: No issues with: C Ci Cim Cime Cimet Cimeti Cimetid Cimetidi Cimetidin imetidine

but nogo with Cimetidine

ditto behaviour with lower case 'cimetidine', so it's case-insensitive ditto crash with ':Cimetidine' and ':cimetidine' (note leading colon for wiki tab), so you can't escape out of it with wiki codes ditto crash with '_Cimetidine' and '_cimetidine', so you can't escape it with leading characters and finally, ditto with 'cimetidine_' and even '_cimetidine_', or ccimetidineee so you can't escape it by right-padding or even embedding internally.

Conclusion: The exact sequence of characters 'cimetidine' (case insensitive) can't be used, even when embedded inside another string!

I've searched Google and Mediawiki for (cimetidine && mediawiki) but no bug reports seem to have been lodged.

Activated debug log but no useful information was apparent.

Wiki can be found at www.chempathwiki.net

Any suggestions greatly appreciated.
