Comment (by ghostofharambe):

 Hi there, thanks for the quick reply.

 It's a plugin that has multiple pages which each one has a shortcode
 inside that calls a specific function in a file that does similar actions
 with all the rest shortcode functions.

 The issue first occurred when we added many new add_shortcode() and we
 thought there was a limit with the shortcodes created in the whole
 installation, because at the removal of one shortcode function and
 references the Front-End was restored (previously some elements will not
 appear).

 After some debugging and enabling the DEBUG mode of wordpress a warning
 message appear telling that the offset from preg_match() has reached its
 limit.

 Then i tried adding a shortcode with $tag length value n
 (n=1,2,3.....1000) and the issue appeared again when the $tag reached a
 certain length.

 From my testing and perspective i reached the conclusion that there is a
 limit to the overall $tag value of the add_shortcode() function.

 I hope this was helpfull, please let me know if i can enlist any more
 details.

 Thank you and take care
