I'm on a shared host, an Italian service named Aruba Business, for information to who knows it.
I have a Magento 188.8.131.52
When I'm trying to upload an image, using the flash uploader, on the product page, at the tab 'Images', the upload do not works (but do not throws visible and or PHP errors).
Server logs about apache shows me this:
[client xx.yy.zz.aa] ModSecurity: Rule 5617888a7c78 [id "214120"] [file "/etc/httpd/conf/modsecurity.d/rules/comodo/06_Global_Backdoor.conf"] [line "20"] - Execution error - PCRE limits exceeded (-8): (null). [hostname "<redacted>"] [uri "/index.php/admin/catalog_product/edit/id/12623/key/a471ebc9afba3d2a8552290364b573eb/store/2/active_tab/group_58/"] [unique_id "XSWfFjpAMKKJySO8Na9veQAAAAU"], referer: http://<redacted>/index.php/admin/catalog_product/edit/id/12623/key/a471ebc9afba3d2a8552290364b573eb/
I kindly ask you if it is possible to set some parameters about "PCRE limits" on .htaccess or in the Magento control panel, to avoid this problem.
Ask if more info is needed.
